hey ok, i've done the research. my sister wants my old 2g iphone, but can't afford the $20/mo data plan. i called at&t, but apparently it is impossible to either 1: cancel data on the iphone or 2: block edge data to/from a non-iphone (i would unlock and use with her current sim). what should i do? 1: unlock/jailbreak and use her old sim and download a program from installer to disable edge 2: is it possible for at&t to block edge? we have family texting unlimited, and the rep i spoke to told me that data cannot be blocked as long as there is any sort of texting on the phone. 3: unlock and somehow block edge without jailbreaking (i would prefer to NOT jailbreak!) 4: get her a different phone and for those who are going to flip a shi- about disabling edge: we have wifi at home, and she has constant wifi at her university. she doesn't have any interest in using mobile internet except in wifi conditions.
