I believe the Xperia and Backflip are being discontinued by AT&T. If I were to buy a 3G phone on AT&T right now, I think the Captivate would be the model to get. I've not looked at the Aria, but, I just put a G1 and G2 on AT&T within the last week and am pretty impressed with HTC right now. http://www.google.com/phone/ http://www.google.com/phone/ might help you a little. If you can get a Motorola Milestone, you can unlock that from Rogers.ca and run that on AT&T and get 3G (Droid 1 'clone').
