Recently I bought a motorola backflip through AT&T. At first it was a great phone, but after about a week or two everything just started slowing down and not behaving like i thought it would seeing as it is an android phone. I upgraded the operating system to Android 2.1 but this did not affect the speed of the phone at all. So i was wondering if there was any way to send my phone back to AT&T and receive a different one such as the HTC Aria..which I hear is much better than the Backflip. I am willing to pay the difference in the two phones if needed.
