The AT&T FamilyTalk plan is listed for $129.99 for two lines. I assume that means two iPhones get voice *and* data, with no extra charge (unless you want texting). However, I've been hearing rumors that the second line requires an additional $29.99 charge for its data plan. So that'd be $159.98 total (exlcuding tx + fees) for two iPhones on the Family Plan (no other phones). Can someone confirm or deny this rumor? I've searched everywhere, and can't find anything definitive.
