After recently jailbreaking my 2g 2.1 iphone, i thought i had worked our all the kinks and problems that usually come with jailbreaking. BUT, friends and family say when ever i call them, i show up "restricted" or "blocked." Now, i don't know if this is an apple/AT&T problem or a jailbreak problem. My guess would probably be from jailbreaking, but who knows.. has anyone had this problem happen to them or know what to do? awesome thankss again!!
