Well mi problem is that last month i got an iphone in china that was unlocked and working with a hong kong gsm sim..
When i went home i tried a T-mobile chip and couldnt get signal..
After that i lend the iphone to a friend who by mistake installed version 1.1.2.
Now its been 3 days trying different way to unlock it but still chouldnt. My IMEI is changed to 0049....
The steps i did where the ones in some forums and youtube. I downgraded from 1.12>1.1.1>1.0.2. and then used the ibrickr and anysim and still everytime i insert the Tmobile sim or any other a message appear saying "This iPhoe must be used with an approved SIM"
So no i restored it and its with the 1.0.2 version..
Any ideas of which are my steps to follow?
Should i use this method? http://hackint0sh.org/forum/showthread.php?t=12052
