Thank you for your help. After spending so much time looking to the best results this was excellent.

el-eckz June 22, 2010, 1:37 am

the redsn0w jailbreak is not compatable with the new release of the official ios 4.0 because its different even thought it has the same name. the new one is more stable and smooth. if you jailbreak using beta2 redsn0w you’ll experience the same slowness and lag you felt in gold master so be careful and i hope the dev team updates their jailbreak

gonledesma June 22, 2010, 2:12 am

Thank you very much!!! It works perfect!!! Thanks for everyone who made this possible!

elizaberry June 22, 2010, 7:01 am

I’ve successfully jailbroken my iPhone 3G (running 3.1.3 firmware with baseband 5.12.01, but this is the guide it linked me to) but I want to use it on TMobile USA, therefore needing to unlock it – when I open Cydia it tells me that there are essential components that I need updated, but when I agree to update it gives me an error that says
“http://apt.saurik.com NetDB: Open nodename nor servname provided, or not known”.
It gives me what seems like dozens of these error messages. In addition, when I follow this guide and add “http://repo666.ultrasn0w.com” as a source, it says:
“Did not Find Repository
The indicted repository could not be found. This could be because you are trying to add a legacy Installer repository (these are not supported). Also, this interface is only capable of working with exact repository URLs. If you host a repository and are having issues please contact the author of Cydia with an questions you have.”

i have jailbroken my iphone 3g using sn0wbreeze v1.6 to IOS 4 (my baseband is still 5.12.1). i have also added the ultrasnow repository to unlock it but it but it always gives me this error mentioned below

Did not find Repository
The indicated repository can not be found. This could be because you are trying to add a legacy installer repository(these are not supported). Also, this interface is only capable of working with exact repository URLs.

what the hell is that?

iPhoneHeat June 28, 2010, 1:17 am

plz note that in Sn0w it’s digit >> 0 (zero) not an alphabet

I have installed the exact repo as mentioned above with 0 on sn0w. Kindly advice?

iPhoneHeat July 6, 2010, 12:46 pm

May be the Server is down!
address is: repo666.ultrasn0w.com
sn0w >> it’s 0 (Zero) not o

btw- address should be there by default. Go to changes tab and hit refresh. If it asks for update go for it.
then go to sources and see if the repo is already there

Luke July 21, 2010, 2:29 pm

try and put in the source sinfuliphonerepo.com then find ultrasnow from there maybe it will work.

John July 26, 2010, 12:54 am

This site linked me to ultrasn0w and it worked perfectly. Unlocked and ready to go. Thanks a million!

alihumayunno1 July 7, 2010, 1:49 pm

after 5-10mins it says no service

Rip_Diggler July 5, 2010, 4:51 pm

Needing help…
I can’t for the life of me get my phone out of ‘No Service’. I have attempted the restore multiple times, jailbroken and installed ultrasn0w about a dozen times now. Everything works fine, I just can’t get service. I have reset network settings, repoped the SIM, Airplane mode, the works…no joy. Reading all other posts, it looks like everyone else had sucess.

Any help would be greatly appreciated. OS 4.0 on 05.13.04

iPhoneHeat July 6, 2010, 12:38 pm

Make sure you’re installing UltraSn0w 0.93

Rip_Diggler July 6, 2010, 4:58 pm

Yeah, Ultrasn0w is version 0.93. It’s the only one I can find on Cydia. I have even tried downgrading the baseband back to 04.26.08 but didn’t make an ounce of difference. I have also tried multiple SIMs just in case. The weird thing is I can’t find any info anywhere in the event that Ultrasn0w doesn’t work! 🙂

Amytron July 7, 2010, 8:28 am

I am having exactly the same experience as Rip_Diggler.
Have tried everything mentioned above, and have searched far and wide for a solution. Really hope there is a solution shortly.

mac_rocking July 9, 2010, 12:47 am

yeh me also facing the same problem.right now i wished i wud have not upgraded to 4.0 firmware coz things were smooth at dat time buddies plz find a way out i am really upset and depressed without my iphone…………………………..

Rip_Diggler July 7, 2010, 4:53 pm

I remember ages ago when the Dev Team first came out with an unlock for the iPhone 3G and they posted a survey on what Carrier you had and if the unlock worked, etc. Does anyone know if they are still doing it for the latest Ultrasn0w version? The only details I can find on the next Ultrasn0w release is for iPhone v4. Maybe the assumption is that the 0.93 unlock is pretty much 100% sucessful? It looks like a lot of people have had success. I can’t find too many posts of people who haven’t.

Amytron July 14, 2010, 1:02 am

I have tried everything as mentioned in this thread, and I still have no service. So just to confirm: I’ve uninstalled and reinstalled Ultrasn0w, I’ve tried resetting network setting, I’ve tried putting on airplane mode then back again… everything, as mentioned by Rip_Diggler

I am in Canada, and when I tried a friends SIM (Rogers and Fido), it works, but when I put my SIM in (Telus) it doesn’t work.

Is there anything I’m missing?

iPhoneHeat July 14, 2010, 1:33 am

may be something with that particular carrier. try a third one to confirm

Amytron July 14, 2010, 1:38 am

I did actually try another friends SIM which was Virgin (same as Bell here), and no service.

When my phone was first jailbroken, with old OS and Baseband, it did work with Telus, so it has worked before. But now that I’ve updated, its not working.

I will keep reading and researching in the hope that something can be done, but I’m not very hopeful at this point.

NoService July 6, 2010, 12:25 pm

i followed through the whole instruction and jailbroken with RedSn0w 0.9.5 b5 via this tutorial (http://www.iphoneheat.com/2010/06/jailbreak-iphone-3g-ios-4-redsn0w-0-9-5-bet/)

everything worked smoothly, installed ultrasn0w, and rebooted. after the iphone rebooted, i put in my tmobile SIM card (also using a TurboSIM underneath the tmo SIM card). through the whole process, the SIM card was not inserted until the very end and at the end, i get a NO SERVICE/NO SIM problem even after toggling with airplane mode, and rebooting. 3G has been off the whole time as well before inserting the SIM card. could it be the TurboSIM tray/chip being used?

iPhoneHeat July 6, 2010, 1:02 pm

don’t use the turbo chip..
simply insert the SIM..
+ 3G MUST be disabled before installing ultraSn0w on T-Mobile..
uninstall ultraSn0w..
turn 3G off
install ultraSn0w.. reboot
if no signal >> Turn Air Plane Mode On/Off

NoService July 6, 2010, 1:05 pm

thanks a lot! i appreciate the fast response too. 🙂 it was the turbo chip causing the No Service/No SIM.

thanks for the guides as well! will come back for guides in the future. 🙂

asdfghjkl123 July 9, 2010, 2:44 pm

Could someone get back to me ASAP on this :

I jailbroke my iPhone 3GS(previously jb with old bootrom) to 4.0 and i want to unlock it too cause im selling it. When i was jb’ing it i put activate iphone and update baseband but now i get no service with my at&t sim. Is it cause i put “activate iPhone”? Does that only apply to a new iPhone which isnt “activated” aka still on the-connect to-itunes screen?

iPhoneHeat July 9, 2010, 2:48 pm

Install UltraSn0w

asdfghjkl123 July 9, 2010, 7:57 pm

Okay so I did that and got back service but it’s a lot weaker than before and I have “No Service” at times any reason why?

asdfghjkl123 July 9, 2010, 8:43 pm

Nevermind it was just my location, full service now ! Thanks for the quick response. 3G must be off during installment of ultrasn0w and usage of t-mobile but what about if it’s unlocked but with a AT&T sim? Will it affect it if 3G is re-enabled?

iPhoneHeat July 10, 2010, 5:22 pm

you can enable after unlock

asdfghjkl123 July 9, 2010, 2:47 pm

Hey could someone get back to me ASAP on this? :

I jb my iPhone 3GS(previously jb w/ old bootrom) to 4.0. I used expert mode and put “activate iPhone” since i plan on selling it to someone who needs it unlocked. I also put “update baseband” since the new ones are unlockable so might as well. But now i get no service on my at&t sim. Anyway to fix this? Is it cause I put “activate iPhone”? Does this only apply to new iPhones that are stuck on the connect to itunes screen?

ali July 12, 2010, 12:28 pm

hi, after installing Ultrasn0w, i get phone service but not the internet service, it says: Could not activate cellular data network
my plan is att and not registered for iphone, and my iphone is 3g, iOS4.0

Ok I just JB my 3G using redsn0w I installed the source repo666 and once I try to install ultrasn0w the progress bar stops bout halfway through and says repo666.ultrasn0w… then it says posix: operation timed out.

I’ve reset the network settings and restarted the phone and nothing.

Does the new sim have to be in in order to install ultrasn0w??

Any tips or ideas will be greatly appreciated


iPhoneHeat July 14, 2010, 1:14 am

I have Iphone 3gs, 3.1.3 05.12.01.. Successfully managed to jailbreak.. and install Cydia.
Then updated the Cydia using Wifi.. but when i try to Install Ultrasn0w… its just not working.. I mean.. i cant find Ultrasnow.. in the applications. I did it multiple times.. and yes.. I did take care of Ultrasn”zero”w. But not able to unlock the phone..

Please guys.. please help. Anybody please reply.

ez July 16, 2010, 12:34 pm

Hi i need help, i have upgrade my iphone from 3.0 to 4.0. I believe it has the old bootrom. Since the upgrade i can’t find cydia apps in the iphone.

Do i need to restore it first? Currently my baseband is 5.13.04. What is the next step? Do i need to jailbreak first or just unlock it?

Thanks in advance for the help.

iPhoneHeat July 16, 2010, 4:50 pm

jailbreak and then unlock..
if it’s 3GS then only way to jailbreak is by downgrading

ez July 18, 2010, 4:00 pm

It’s 3gs so how do i downgrade? Thanks in advance

i did already reinstalled the ultrasn0w then reboot it and after that i inserted my sim and its still got the same.. ” different SIM detected”just slide for emergency again. but i notice i seeing the cellular name and its signal bars, by the way im from philippines.i dont think if thats the cause

max August 5, 2010, 8:51 pm

I have exactly same problem. And I cannot do anything without original sim car. The screen just locked. Can any1 help us out, plz?

dave August 6, 2010, 7:06 am


I’ve been experiencing the same problem and been restoring my iPhone for more than 5 times now, still seeing the message. Following the iPhone Activation Without Original SIM Guide doesn’t apply to all iPhones, and I dunno why, but now I get my phone working well. See below.

Use redsn0w from iPhone dev team.
1. Restore your iPhone to 4.0.1 from iTunes.
2. Use redsn0w by pointing to the fw 4.0, not 4.0.1 (this will hactivate your iPhone) then you don’t need to activate from iTunes anymore. So you need to have both fw 4.0 and fw 4.0.1 in place to do.
3. Go to Cydia, let it update the necessaries. Sometimes, it’s a must to update things before you can do other things. Reboot, if required.
*** If you’re on T-Mobile USA, disable 3G.
4. Go to Cydia again, add repo666.ultrasn0w.com, install ultrasn0w, reboot. This will allow you to use any carrier SIM. Bravo!!!

I had upgraded my iPhone 3G when iOS4 came out. I have since gone back to 3.1.3 (7E18) since the phone had became so slow it was unusable. After the downgrade, the baseband version remains 05.13.04. Does it mean that I am stuck in limbo and must upgrade again to iOS4 if I want to jailbreak and unlock my iPhone? All the solutions I read about refer to iOS4-05.13.04 or 3.1.3-5.12.01.
Thanks in advance for any advice.

My 3gs iphone is still on the 3.1.3 version with the 5.12.1 firmware. Can I update it to the 4.0 version now? And still have it be unlocked, or do i have to download the new unlock for the 4.0 system- is it even out yet?

vivoniv September 8, 2010, 5:21 am

Hi everyone, got my 3GS 16G off ebay, it says jailbroken and unlocked but when I got it I still couldnt use my sim card(from another country).
Instead of getting a Phone Book sim card and unlock it, I used an inactive sim card (a sim card that hasnt been used for a very long time, or a brand new sim card that hasn’t been activated, you can check it when you insert it to a normal phone it says inactive sim etc).
So I put the inactive sim card in, installed ultrasn0w using Cydia, wait patiently for it to finish. Then only i reboot it. (Note: I turned off my 3G)
So when my phone restarted itself, the inactive sim card was still in there and the screen says ” Waiting for activation. This may take some times”. So I waited for like 15 minutes. Switched off my phone. Took the sim card out, and put my own sim card in (the one that you wanna use). When I switched on my phone again, it says ” Phone activated”.


Hope that helped. Cheers everyone!

I just followed the instructions above and unlocked my 3G running baseband 05.13.04 and IOS 4.0.2.

I first had tried a jailbreak with redsn0w, which seemed to work, but was unable to activate the carrier. Thus no phone.

But now it works.

This site was very helpful. I got a lot of stuff done, but I still cant use my tmobile sim.
I have a iphone3g, 8gb. It has ios4.1 on it. I followed all the instructions on jailbreaking it. In the end when i restored it with itunes, it gave me a error message that it was unable to restore. But the fone is jailbroken, because when i took it out of dfu, it had cydia and other apps that it didnt have before. Now i tried unlocking it, and i followed the instructions, i went to cydia and installed ultrasnow. it installed correctly , but when i put my sim, it says no service, even after i turned 3g back on.
Can someone help me?

I have iphone 3gs new bootrom and i did all the steps that are required for 3gs new bootrom, and im pretty sure that i did them correctly. However, when i try to choose the IPSW file that sn0wbreeze created for me, itunes tell me: The iphone “iPhone” couldn’t be restored. An unknown error occured (1600).
