Regarding the "$10 data plan", I don't think that you'll be able to qualify for that on T-Mobile, with a T-Mobile branded phone, if that was your goal. A T-Mobile branded phone on AT&T's network would qualify for AT&T's $10 plan
I have T-Mobile (don't plan on going anywhere yet) and I know I can have the $10/month DATA with it, as I had it when I first bought the G2x back in the spring/early summer and took it back, unless you know something I don't know?
I did try searching the forums, but the search thing took over 45 minutes more than once in different browsers all did the same thing. So that is why I posted here. Perhaps you can send me that link of your post? I would love to read more about the phones before we choose again.
