I am on AT&T and my 3gs has bit the big one. I have been having issues with it for the last several months and wanted to replace it with an android phone. I know the backflip is the only android phone available at the moment, but is there any other phone from another carrier that can be used on AT&T. I also have a google voice number and I feel like I am missing out with my iphone and that I cannot use my GV number to it's fullest potential. Thanks.
