Hi All,
I unlocked my 2G iphone (2.1) two weeks ago, every thing was going great until one day I could neither get outgoing/incoming calls. Everytime I make a call I hear no tone and it says call ended , call failed after 10 seconds, same for voice mail. I dont get incoming calls either it goes directly to voice mail or some times rings on the caller side but no rings on the iphone

. The signal is full and the carrier shows AT&T
I tried restoring a couple of time but to no avial, I unlocked it using WinPWnand even tried restoring after DFU mode.
Please help!!!!
Thanks
