AT&T begins shutdown of AMPS and TDMA networks {Engadget Mobile}

Jul 14th 2007 12:34PM I understand that we must all upgrade our phones but how can they force us to upgrade our plans. I have a plan now with 1100 minutes for 49.99 and they are saying i will have to go with the going rate plans. i have even agreed to sign a 2 year contract, buy a new phone if I can keep my current rate plan.
