i got a new 113 two weeks ago. it has bootloader 4.6. i have a current valid at&t sim but not for iphone. how can i use this sim with my iphone without activating an iphone contract? do i have to downgrade to 111 to unlock. i heard phone function will be lost... please reply asap. i am sitting with this phone for two weeks now.
if by mistake i downgrade to 111 and lose phone function, can i upgrade it back to 113
