It was OOB 1.0.0 and is now running 1.1.1 and it was jailbroke and unlocked and using T-Mobile then I turned it off and back on and now it isn't working anymore. Everything was working, youtube, the internet, text messaging, etc. Any suggestions? Do I just have to never turn my phone off or what?

whats not working?
its not clear what the problem is
does it turn on? can you open any apps?

It turns on and all applications work, but the phone and internet isn't working

do you get network?
im not sure, you could try a restore as a last resort...

No network connection, I will have to restore as a VERY last restort, but has anybody else had this problem?

I tried The Virginizer, then restoring it, then installing App Snap, then AnySim, & then it says your iPhone has been successfully unlocked, but then when I soft reboot it it says Different SIM Detected, Please connect to iTunes. I don't know what I am doing wrong, because I did the same thing before and it worked fine, now I can't seem to get it right. I tried the SIM card in another phone and it worked fine. Any suggestions will be well appreciated, thanks.

It's because ur iphone is itunes activated. It doesnt matter when you downgrade to 111 and itunes activate it, but when you update back to 112 and itunes tells you ur iphone is rebooting. Close itunes and run the jailbreak software, it will activate and jailbreak ur phone, then u run anysim 1.2.1u while ur phone is in airplane mode and ur foregin sim is in it. Your iphone should work now.

The point is that, whateva firmware ur trying to run the phone unlocked on, u cant have it itunes activated on that firmware, it have to be the *#307# for 111 and the windows.bat file or jailbreak.jar file for 112.

Hope this helped.
