I plan to upgrade to the new G2x (assuming it does actually have the AT&T bands on it) before the takeover, so I'll get to keep my old rates AND get a great big screen with dual core processor
My biggest worry was that if I had to get a new phone to work with the ATT&T 3G and 4G, I'd be forced into a new contract to get the phone at a reasonable (discounted) price. I've read all the stuff at the ATT&T and T-Mo sites, and I didn't see anything that said you'd get the old rates if you needed to buy a discounted new phone (that would require a new contract). AT&T may still decide to do something like that to keep existing T-Mo customers happy and onboard, but being able to upgrade to a compatible phone before the acquisition just eliminates that worry for me. (Plus it gives me a "reason" to upgrade to the latest greatest--I can rationalize with the best of 'em)
im hearing all new plans for att and alot will match tmobile, lowering the in price plan for current AT&t people as well
