I have 3G and I’m wondering that if I have upgraded my iphone 3G to ios4, should I activated ??

The latest RedSn0w 0.9.5 b5-3 can hacktivate 3G at iOS 4.0 so you can then install ultraSn0w from cydia

Hi, i have a little question, my iphone 3g have a 05.09 baseband, can i unlock my iphone if i updatee to iOS4????
Using custom firmware is recommended way..
However iPhone 3G users can also use RedSn0w to jailbreak iPhone 3Gs iOS 4 and the UltraSn0w to unlock it 🙂
I am currently on 3.1.3 on my iphone 3g.
I want to unlock my phone, shall I update it to iOS4 and then unlock it?
You can do so because latest baseband 05.13.04 is unlockable now.. however i recommend to go for custom firmware.. create one urself or checkout the iPhone firmwares category 🙂
i unlocked my iphone 3g os4 with ultrasnow but after that i am getting no service error sometimes i get the network service and suddeny it gooes away saying no sim installes plz help me
settings> general> network
and turn off 3g and data roaming
OK guys, I spent 12 hours with no sleep doing the jailbreak and unlock of 3G iPhone because it was upgraded to 3.1.3 before I decided to give to my wife when I bought the new iPhone 4. Here’s the deal – I tried everything, and I mean everything and I read all these posts. In the end I sat here disappointed 12 hours later with no service on T-Mobile USA. And occasionally it said – waiting for activation. BUTTT!!! after all that, 4 hours ago I broke the phone in my attempts and so was forced to upgrade on iTunes to OS4 – gone were my hopes I thought. But no, it carried on looking hopeless even though I followed the redsn0w and cydia ultrasn0w instructions to the letter. And then, quite miraculously even after getting a new sim card, a little message popped up and it said ‘activation complete’ and immediately, and I mean immediately I had full signal and the magic word T-Mobile smiling at me. Redsn0w the beta new version and ultrasn0w .93 DO WORK, but you might have to wait it out with the phone on while the activation takes hold at least here in the US – maybe it is just because of the sheer weight of iPhone purchases in the last 2 days, but I can tell you, it works so Dev-Team and Cydia guy, you are marvelous and we love you!
+ make sure you disable 3G first before installing UltraSn0w
i’d updated from fw2.2 to ios4 and successfully jailbreak/unlocked my iphone 3g with redsnow4/ultrasnow. but when i tried it to my sister’s iphone 3g, i’d jailbreak it but when i installed ultrasnow from cydia and reboot it, i am getting no service. i did turn off 3g as the steps saying, could you help me how come its getting no service?
try turning off data roaming as well
plus wifi on off
and reboot.. still out of luck?
reset network settings
or turn data roaming + 3g off and reinstall ultraSn0w
same thing happened to me and i resolved it the above mentioned way 🙂
the iphone is already unlocked, its just the simcard was kinda loose…stupid me. anyway, thank you mate, at least you’re willing to help here.
how did u fix the loose sim card because i think im having the same problem!
Hey Guys, I’ve just jailbreaked my iphone 3g ios 4 baseband 05.13.04 and I’m currently trying to unlock it as well using ultrasn0w. I launched cydia and added repo666.ultrasn0w.com and installed ultrasn0w however it’s still locked. I reinstalled ultrasn0w many times after disabling 3g and resetting network settings however the problem still persist. Will be thankful for your help!
same problem!!! still locked asking for “enter pin 3 attempts remaining”
forget it. it work like magic!. the sim card, it self ,was the problem…
i have a iphone 3g on 4.0 bb 6.4 fw 05.13.04 i jailbroke it with redsn0w .09.5b5-5 and was successful i tried to unlock it with ultrasn0w but had no success i turned off 3g i reseted the network and still it says no sim installed….. with that said i put a friends att sim and it said no sim installed so what do i need to do?
There’s something wrong with the SIM (inserting)..
otherwise it should say >> No Service
uninstall UltraSn0w then insert the SIM and see what it says
i still get the same thing….. but when it was on 3.1.3 it recognize the sim card fine and now that i upgraded im having problems
hi i just wonder why most people are able to unlock their iphone 3g. i have try many way and times but still not sucessful. Is there anyway other ways that i can try to unlock it .
it’s been 1 week i’m trying to unlock my Iphone 3G OS4 BB 05.13.04 BL 5.09 but still i ‘m stuck at “NO SERVICE”
I’ve been following step by step Iclarified’s tutorial at least 4 times. I’ve started from a stock IOS4 JB with redsnow 5-b5 then installed ultrasn0w 0.93.
My further not successfull attempts were:
– 2nd jailbreak without installing Cydia
– installing ultrasn0w without 3G, data network etc..
– how swap with a different SIM
Unfortunately it seems i’m not getting any good result so far. Also googlin “ultrasn0w 0.93 no service” i came across other users experiencing the same issue.
Guess i might wait for Fuzzyband new version to downgrade the BB with BL 5.9 or other stuff.
Any ideas ?
Turn 3G off
Install ultraSn0w 0.93
turn air plane mode ON/OFF
still not working?
reset network settings
once you get signals, you can turn 3G back on
Nope, it doesn’t work.
It’s a week I’ve been trying all these tricks, with no success.
And every day more and more people are experiencing the same “no service” issue.
There might be something between some SIMs and ultrasn0w 0.93.
It worked for majority..
Indeed, i’m rather confused.
I’ve also made the following:
– checked that IMEI wasn’t blacklisted
– I’ve installed a new 3G antenna module
No results so far. Of course..
have you fix the no service problem? i need help with my 3g iphone too

I have successfully installed 3.1.2 but now i cant make it unlock
I jailbreaked it using blacra1n

Cydia>installed ultrasnow>Reboot…after that No service :s
go through all the comments
I have an iPhone 3g running ios4, unlocked with ultrasn0w .93, but having the problem with no service along with everybody else. Have tried uninstalling/reinstalling with 3g off, and basically everything else mentioned. Does it matter when in the process the tmobile sim card is inserted? Have we found a sure fire fix for this problem yet?
Ive checked with the local corner shop mobile unlocker he says that my basebands unlock isnt yet arrived :s
my baseband is 5.13.04
Is it 3G?
if yes then use RedSn0w to jailbreak and UltraSn0w 0.93 to unlock
yes its 3g
its already jailbroken but cant unlock it
ive tried several times but it says
No sim or No service :s
turn 3G off
turn air plane mode ON/OFF
I am on ios 4.0.1, the unlock doesn’t seem to work.
Anything you’d like to share with others on what caused the prob. will be highly appreciated
Is the ultrasn0w repo down? Everytime I try to download ultrasn0w it fails. I tried with cydia and with rock…
Anyone else having this problem?
use .org in place of .com if it’s down
I finally done it, I fixed the No Service 😉 I tryed so many things & this worked for me:
1. Go back to 3.1.2 in iTunes (1050 error is no problem)
2. go to blackra1n.com and “let it rain”
3. install Cydia in blackra1n app
4. ultrasn0w repo in cydia
5. download ultrasn0w
6. reboot & after a minute my Service was back
hope I could help, greetings from Austria

Hi! i have a iphone 4, with 4.0.1, i unlocked with ultrasn0w, got service, got 3g, but i got very low signal strength, and when some call me, they cant listen to me, when i call them they dont listen to me, i have to call twice for it to work, what can i do??
uninstall and then reinstall ultraSn0w
Yes, i already did it, but if i called someone i can hear them but they cant hear me, so, i reinstall again, and it was working great, and then i installed MyWi and the phone reboot, after that reboot the 3g was not working, so i reinstall again ultrasn0w, but i havent been able to recover 3g… 3g not working…
everything works now… but it worked fine for like 2 days, now when i make a phone call the other people dont listen to me… what can i do?
Same problem here.

Apple upgraded the modem firmware to 05.14.02. If this is what you have now, which I assume you do since you went to 4.1, the modem FW CANNOT be downgraded just yet. So right now there is no J/B for this baseband. You’re just gonna have to wait like the rest of us for the guys at the Dev Team to come out with a new Jailbreak.
