Yes, your phone is blocked by the network.
You can’t use it where you live, sell it to someone in another country.

iPhoneHeat November 4, 2009, 1:45 am

here’s a lil. addition to the tip
For T-Mobille you need to disable 3G too..

itouchipod November 5, 2009, 5:58 am

I have a few questions. I had my phone originally jailbroken through quikpwn. Do I have to re-jailbreak for this to work? I downloaded blackra1n through Cydia, but I didn’t see a blackra1n icon or app logo on my iPhone. Did I do something wrong? I inserted my t-mobile card, but it still said no service and I couldn’t make any calls.

iPhoneHeat November 5, 2009, 4:02 pm

You need to perform a simple restore @ 3.1.2 then jailbreak using BlackRa1n and then unlock using BlackSn0w (Make sure 3G is disabled)

itouchipod November 5, 2009, 6:01 am

Someone please help I am in urgent need….P.S( Geohot you Rock awesomely dude… u have turned me into a believer dude… thnx for all your work…) Still having a little trouble unlocking my iPhone but thanx anyway…./.

ahmad November 4, 2009, 1:46 am

iPhoneHeat November 4, 2009, 2:06 am

Follow the jailbreak guide link in the start of this guide..
yes you need to update.. then jailbreak and unlock

user1 November 4, 2009, 4:44 am

Trying to install via Cydia but consistently getting the following error:

Sub-process bzip2 returned an error code (2)

Note that I already jailbroke using the original blackrain and not RC3

iPhoneHeat November 4, 2009, 2:02 pm

Then why not perform a simple Restore and user BlackRa1n RC3..
If you already have on your iPhone then simple follow the first two screenshots about updating and then using blacksn0w

rewl86 November 4, 2009, 3:19 pm

ammar November 4, 2009, 10:32 pm

hi.. I have just jailbreak and unlocked my iphon with blackra1n n installed cydia, worked like a charm… but all my apps n games don’t work. Once you click on an app it comes up for a millisec and gone! pls help

iPhoneHeat November 4, 2009, 10:36 pm

ammar November 4, 2009, 10:55 pm

do u have any idea what is going wrong??? pls help me..

iPhoneHeat November 4, 2009, 11:00 pm

Try a fresh restore and jailbreak again.. It’s kinda new to me
Try resyncing Apps

ammar November 4, 2009, 11:34 pm

bro i have tried before what did u mention just now but the problem still same,, after that i downgraded to 3.0.1 jailbreak again all apps worked well, just unfortunate that blackra1n not working with 3.0.1 to unlock my iphone…. so pls if there’s any resolution just update me


Faz November 5, 2009, 12:57 am

u need 3.1 or 3.1.2 for blackra1n and blacksn0w to work.
First u’ll need to update ur phone via iTunes to 3.1.2 then jailbreak then unlock then re-sync
All should work fine.

Sayyar November 4, 2009, 11:21 pm

Thank you very much
and easy step to unlock your Iphone 3GS 3.1.2

Thanks to Geohot

iPhoneHeat November 5, 2009, 2:50 am

thanks for the input faz

Rich November 5, 2009, 7:39 pm

Is it possible to know if my phone 3gs was unlocked using blacksn0w without using another sim, which i don’t have. Redsnow on my old 2g had added a tab in settings called carriers. Thank you for your time.

popotamito November 7, 2009, 2:57 am

Hi, does anybody know if is normal having JB the iphone with BlackRa1n after shutting down and trying to turning on, indicate that I have to connect it to itunes, so what I did is JB again with BlackRa1n and star working again. My question is there anything that I can do to avoid that process, meaning a normal turning on?

Tato November 8, 2009, 9:27 pm

yeah that’s exactly what had happened to me so please …
guys we have the same prob can anybody help us ?

iPhoneHeat November 8, 2009, 9:45 pm

The latest iPhone 3GS units supports tethered jailbreak only which means everytime you restart/turn off your phone or it goes Off coz of power outage.. you need to jailbreak it again 🙂

Tato November 8, 2009, 9:58 pm

so that’s will b for good ?
or we should expect solution nearly?

iPhoneHeat November 8, 2009, 10:38 pm

all depends on Dev-Team/GeoHot..
There’s no time frame of releasing a permanent jailbreak for latest 3GS units .. sorry

Tato November 7, 2009, 8:49 am

I just bought an IPhone 3GS from apple store with no contract but it’s locked …. when i powered it on it says connect itunes’s my first time to iphone and i wanna do it myself as many of my friends recommended you to follow

Thank you again.

kissme November 8, 2009, 11:57 am

i did everything it told me to do. I jail broke my 3G iphone with no problems and unlocked it with blacksn0w. All my apps are running fine as well as my wifi. Unfortunately one problem. I have no service, I am from canada and using a rogers sim card. everytime i press airplane mode to on and off it searches but doesn’t find any carriers. Now my phone can’t make calls 🙁 I seriously need help. What have i done wrong?

iPhoneHeat November 8, 2009, 8:52 pm

Did you reset your network settings?
Settings > General > Reset > Reset Network Settings

kissme November 10, 2009, 10:23 am

yes i did that as well but same thing…my only option now is to go out and get a new brand new Iphone 3Gs but i really don’t want to:( What a waste of a phone!!! Any other options? Is there any possible way I can fix it or go back to a 2.2 version?

kissme November 10, 2009, 10:30 am

Also when it detects my carrier it does have rogers with a check mark but it still says no service. Then when i go to About…where it says carrier it says carrier 5.0. When it searches for a network, most of the time it pops up a message saying ” Network Lost. Your selected cellular network is no longer available. You can choose a different network in Settings”
I really screwed up my phone haven’t I? PLEASE HELP!!!!

iPhoneHeat November 10, 2009, 5:33 pm

No need to get a new one.. We can fix it.. Only thing you need is patience..

Why not reinstall BlackSn0w.. if you did it via BlackRa1n why not download this time from Cydia?

and after install.. Reboot your iPhone.. Got signals? NO? Reset Network Settings.. your phone will reboot ..
come back with results

dzamala December 8, 2009, 12:10 pm

I have the same problem. I have an ipohne 3g os 3,1,2 jb with blackra1n and tried to unlock with blacksnow and cydia too. But the No service still remain.
I’ve already reset my network setting also; I’m really desperate please can u guys help me with my precious.
Best regards

iPhoneHeat December 8, 2009, 4:07 pm

if it’s Tmobile then turn 3G off.. then install blacksn0w..
also reset network settings in the end

freepass December 19, 2009, 8:09 pm

HI,I had to wait almost 10 min for the different carrier’s network to pop up…Just like *iPhoneHeat* said before: you gotta be patient:)

iPhoneHeat December 19, 2009, 9:25 pm

thanks for the input..

ipoditouch November 9, 2009, 11:05 am

I had quikpwnage and blacksn0w on my iphone 3g S, but because I was unable to get Youtube, Internet or GPS to work. I have restored it. I tried using blackra1n to jailbreak, but no success. I guess because I don’t have an AT&T sim card it won’t let me continue. It sent me to connect with iTunes screen. How do I bypass this? I even got it to DFU mode but still no success. Please help!!!

iPhoneHeat November 9, 2009, 7:03 pm

What happens when you try BlackRA1n?

ipoditouch November 9, 2009, 7:21 pm

it goes through the whole process and even through make it ra1n, but nothing happens… the iphone screen remains the same. i did the original restore and even insterted an unactivated att sim card but no success with the jailbreak. it did however, get it out of the “connect to iTunes” part

iPhoneHeat November 9, 2009, 9:26 pm

Hold down the both home and Power buttons at the same time.. keep holding until iPhone reboots and turn back on with connect to iTunes screen..
iTunes will detect your iPhone in recovery mode..
if it doesn’t atleast it will ask you to let iTunes check your iPhone model.. Press the check button..
Once your iPhone is detected by iTunes.. Perform a Fresh restore..
Once done.. you will be stuck at emergency screen..
now again put your iPhone into Recovery mode by Hold down the both home and Power buttons at the same time until you get to the connect to iTunes screen..
this time run the BlackRA1n.. and come back with results..

ipoditouch November 9, 2009, 11:06 am

I tried several times and in 2 occasions I got an error 1600. I am not sure what am I doing wrong. Any suggestions?

ipoditouch November 10, 2009, 6:05 am

iPhone heat ur a genius…. it worked ur awesome!!! it work im gonna try the rest of the process and get back to you….. thanks dude!! u rock

ipoditouch November 10, 2009, 6:50 am

Okay, it worked, but now Im having the same problem with the internet, youtube and gps. I downloaded and even got the newer “push fix youtube” but it still doesn’t work. The internet is not working I am going to try this same process again and hope it will work.

ipoditouch December 1, 2009, 10:37 am

I finally fixed my problem. The problem was that after entering the information from tmobile. I was suppose to turn wifi off and 3G then turn phone off and turn it back on to fully operate.

lololabrute November 18, 2009, 7:27 am

So, here’s a new one for all of you :

I have a new 3G S, have installed blacksnow and all is working fine (i’m in canada, using Fido sim card) except the tethering when I am using the bluetooth function. Tethering only works when the phone is plugged to the computer. As soon as I try to the same with the phone unplugged, I lose the connection 2 seconds later (i get the “no service” sign).

Any pointers re this?
otherwise, i have no wifi problem, no gps problem. Only the bluetooth tethering.

If anyone has a clue, please let me know.


ReeF November 29, 2009, 10:03 am

I have jailbreak my 3gs 3.1 using custom restore 3.1.2 and it went ok. I got cydia on my iphone.
Then i followed the steps-by-steps above by downloading blackrain thru cydia. Then it says PROFIX: Operation timed out. POSIX: Operation timed out.

Help me pls…

iPhoneHeat November 30, 2009, 12:24 pm

Custom restore is much better way imo..
did you perform a simple restore using Official IPSW file or trying blackSn0w on custom firmware?

iphoneuser November 29, 2009, 10:13 am

I have a new 3G 8GB iphone from AT&T , I tried to Jailbreak and unlock it as suggested in the web page. I did not see much error messages on the process, but now when I tried your DiskAid tool, When I go to root folder it gives me a warning that only jailbreaked device can show the root partition, I am able to see the root partition but with limited folders.

I am not able to set wallpaper anywhere , even if I set it is just displayed for 0.5 sec when I restart the device.

please advice how to reset and make sure that I have unlocked the phone.
Maruthi S

iPhoneHeat November 30, 2009, 12:25 pm

Perform a Simple restore using Official firmware.. then use BlackRA1n again

iphoneuser November 29, 2009, 10:18 am

adding more tech details about my unlocking process.

3.1.2 (7D11) and modem firmware 05.11.07

i did not turn off wifi when doing the jailbreaking and unlocking process.

I have tried both the method blackrain and Cydia, I have tried with cydia method after closing the wifi to off mode.

please help me in unlocking my phone.

I have a 3GS 32GB, from juli. 3.1.2; baseba 05.11.07 It comes from Italy so it has no simlock.
Can I jailbreak the phone with Blackrain. Does anyone has experience with this situation?
Thanks for reacting.

iPhoneHeat December 1, 2009, 1:59 am

go ahead

craighjones December 2, 2009, 5:41 pm


Experiencing the same issues, My iPhone is jailbroken with blackra1n and unlocked with blacksnow and I’m using Orange as a carrier within the UK.

WIFI works fine and so do calls until I loose a signal, then I have to insert my SIM into my old phone and then back into my iPhone and boom! A full signal.

I’ve just returned from Amsterdam where I used my Orange UK SIM and iPhone connected to a Dutch carrier experiencing no problems at all even when I lost signal.

Why would this happen?


iPhoneHeat December 2, 2009, 8:01 pm

Insert the SIM and reset network settings..

lazarog112 December 8, 2009, 10:43 pm

I purchased my iphone 3gs 1 week ago every time i jailbreak it and i install winterboard after it reboots it crashes and I have to restore it back thru apple why is this happening?

iPhoneHeat December 8, 2009, 11:34 pm

Because latest units are tethered jailbreak only.. which means you need to run blackra1n on each reboot

lazarog112 December 9, 2009, 1:38 am

thanks very helpful, it worked

lazarog112 December 8, 2009, 10:48 pm

I have it with AT&T

iPhoneHeat December 19, 2009, 7:23 pm

Because you purchased 3GS after September. the latest units are tethered jailbreak only.. means whenever you’d reboot your iPhone (you lose jailbreak) you’d need to run blackra1n again

sai December 27, 2009, 3:42 pm

thanks iphone heat

FreePass December 25, 2009, 9:03 am

Hi there,
I just jailbroke another 3GS 16GB and unlocked it as I always did.At this time I just swap out ACTIVE ATT Sim-cards and the iPhone went into emergency mode saying it doesn’t recognize a sim-card.As soon as I put back the original sim-card with which the iPhone was activated via iTunes and the phone works again!.I never had this problem before and I jailbroke/unlocked multiple iPhones.I don’t understand what’s seem to be the problem with the unlocking?:(
Thanks in advance

iPhoneHeat December 25, 2009, 10:14 am

it’s strange..
why now reinstall blacksn0w while putting in the Sim which is not working.. ofcorse you need to run blackra1n to bypass emergency screen

FreePass December 27, 2009, 7:33 am

Hey iPhoneHeat,
I connected an iPhone to iTunes with a different working ATT Sim in order to run blackra1n.The phone went dead…I tried to restore it and it’s still dead only with a white screen at this time.Then I tried to restore again with the original Sim card from DFU mode- no response.And the window within iTunes saying:*Defective Phone blah blah blah*.Tomorrow morning I am shipping it back for exchange for another one.
So it was very interesting experience….

iPhoneHeat December 27, 2009, 10:10 am

Never read anyone saying that he encountered such error from iTunes..
One of my regular readers, is the first one reporting it.
can you please send me a screenshot? I really wanna see it 🙂

freepass December 27, 2009, 7:44 pm

sure I will send you a screenshot without blah blah though:)

FreePass December 30, 2009, 4:36 am

Hello again,
I got the new iphone and followed your directions from this post.But strange things are happening again:the phone is unlocked and showing a sim card from different carrier,but the screen remains in the Emergency mode.However,I can make a phone call TO my phone and even have a conversation,but I cannot dial out due to the emergency screen.Is there way to resolve this please?
Thank you.

FreePass December 30, 2009, 4:40 am

I forgot to mention that together with an emergency screen there is a message saying “Different SIM detected.Please connect to iTunes”. So I did and iTunes is telling me that my phone cannot be activated.Wonder why:)

iPhoneHeat December 30, 2009, 9:10 am

Your phone is NOT jailbroken

FreePass December 30, 2009, 11:32 am

was it addressed to me? if yes,what can I do to complete jailbreak? Remember,I’ve done it multiple times and this is first time happening to me.

FreePass December 30, 2009, 12:36 pm

By the way, I jailbroke my gfd’s iphone,my own and this one, all in about the same time( within a couple days),and only newly arrived refurbished phones acting the way I explained earlier.If I keep an original sim in the phone and reboot it after jailbreak,it doesn’t go into recovery mode.So I know these phones were operational before September 2009.
So any idea on what might be the problem??

Kmahirz December 25, 2009, 1:13 pm

Hello iPhoneHeat my problem is that the wifi is not working on my iPhone 3G 3.0.1 but its jailbreaked now i do not know how to unlock the iphone without wifi. DiskAid works on my pc (Windows) but it does not showing the contents of the iphone.

iPhoneHeat December 25, 2009, 5:07 pm

you can get WiFi back by resetting the network settings
Settings > General > Reset > Reset Network Settings

@ baseband..
there’s no need to downgrade because it’s unlockable now:

Kmahirz December 26, 2009, 10:36 pm

I’ve already reset the network settings but no wifi found, infact i am looking the thing to unlock my iphone without wifi and internet or is there any other way to use my windows pc internet on the iphone! kindly guide me if there is any chance to . .

If you’ve updated your iPhone to 3.1.3 BB 05.12.01 then you’ve made a big mistake as there’s no unlock or jailbreak as of yet and maybe never.

In the process of attempting to update my iPhone (3.1.2/ 05.11.07) to iOS 4.0 by myself. It’s already unlocked through blacksn0w for the 3.1.2 update. For some reason the internet is not able to load. I’ve tried different codes for APN but now there is no where to put APN codes. (pic messaging not working either). In Cydia I have downloaded different carrier bundles but I can’t get anything to get internet. Not even WiFi is getting picked up at this point. I’ve noticed I have Dev-Team with yellowsn0w installed under Cydia.Help please! =(
