[shinganova]

ok my iphone is version 3.0 modem firmware is 04.26.08 (its been updates since i jailbreak and unlocked) i unlocked on version 2.2.1 i think.....)


i have all ready jailbreak the i phone and unlocked it! but i still cant make phone calls and text. I am using a t-mobile sim i am getting full signal but still cant make or receive calls as well as text. i have been wondering if the iphone is blocked but i am not sure how i can tell. anyone got any ideas on how to fix this??

Have you tried turning off 3G?

Also check that you have the correct carrier/APN settings.
