    Question Unlocked/Jailbroken Iphone 3g "No Service"

    Have an Iphone 3G 4.2.1 and had it jailbroken and unlocked using greenpoison and redsn0w by a friend so I'm not sure what versions were used.

    Using Tmobile sim I now have the dreaded "no service". (Sim works in tmobile phone). Have seen literally hundreds of fixes and nothing works. I've tried turning on and off airplane mode (while taking out sim). Reinstalled ultrasn0w. 3G is off. Turned off cellular data, turned off updates from social networks. Nothing is working. I'm not even sure if my phone is really unlocked/jailbroken at this point.

    Someone said to get a new sim from tmobile? Mine is about 4 years old, anyone had luck with this? Any help would be appreciated. Thanks!

    What baseband is on the phone? Did anything change between it working and it not working?

    Thanks for responding. The baseband is 05.15.04. I just bought the phone used from a friend who had AT&T, worked fine for them. I didn't change anything except for jailbreaking and unlocking. I haven't been able to get it to work with my t-mobile sim at all

    There's your problem. 05.15.04 is not unlockable using ultrasn0w -- your only option with this device is to (NOT RECOMMENDED) upgrade to the iPad baseband of 06.15.00. The problem with this is that there's a high likelihood that it will break your GPS, and once you've done this, there is ABSOLUTELY NO WAY TO GO BACK. Can't stress that point enough, there are a lot of people on the forum asking for ways to downgrade and the unfortunate truth is that you cannot. This is truly a last-ditch method to unlock. If you can hold on, you may want to wait until November to see if they release a new unlock for the previous basebands. It will likely be November at the earliest, as they will not want to burn an unlock before the 4S is in everyone's hands with finalized hardware. Cat and mouse game, you know.

    Oh man, that totally sucks but I'm so glad to know what the problem is instead wasting my time trying all this stuff that will never work. Thank you so much for clearing it up for me. Hope they put out a new unlock soon!

    That said, MuscleNerd did just say that they think they will have a way to downgrade this baseband sometime in November, so there is the possibility of a downgrade in the future. Not enough of a possibility that I'd recommend upgrading, but there is at least hope!
