Hey guys I bought the 3GS last year on release date and I'm one of the unlucky people to be stuck at the 2/20/2011 until full discount upgrade pricing with AT&T.. However, my mother's contract just ran out with Verizon. She prefers dumbphones. So I was wondering, when the iPhone 4 is released can I go to AT&T and make my plan a Family Share plan, add her a line and get the iPhone for $199 on her line, switch the i4 with my 3GS, then just sometime later tell AT&T I broke the iPhone on her line and just buy her a dumbphone with a SIM card again? Or will AT&T be very anal about removing the (now useless) data plan from the line? Has anyone tried something like this know how AT&T will react?
