I have successfully unlocked my firmware 1.1.2 iphone from using the tutorial here http://www.hackint0sh.org/forum/showthread.php?t=28789
when i insert my country's sim into the phone (malaysia). The iphone detects my service provider with full bars, but whenever i attempt to touch the "phone" option in the main menu, it would go to the number page where I can dial numbers, but it wouldnt let me type anything. After that it suddenly goes back to the main menu.
My phone also cant receive calls but it can detect whenever an incoming call is present. The screen would hold and the loading sign will show.. but thatís about it. After the incoming call ends. The iphone can also detect the miss call, but wont let me trace who called me.
Any help would be appreciated
