Recently, I dropped my blackberry curve 8900 into a pool and needed to get a new phone. Im a teenager and dont really need a blackberry so I decided to get the Motorola Backflip. I had to terminate my old line and add a new one. I got the phone for $50.00 less at Best Buy then at my local att store. As its the first android phone on att, it had a lot of problems. My battery didnt last more then 4 hours. So I brought the phone back and having had an iPhone 3g a while back, got a 3gs. I then heard about the release of the iPhone 4 and needed to have it as I didnt want to be stuck with a 3gs for 2 years. I was able to bring that phone back to Best Buy too and exchange it. All I had to pay was a $10.00 restocking fee. AT&T only allows for one exchange.Also, best buy offers a better insureance policy then apple does!! I LOVE MY IPHONE 4!!!! THANKS BEST BUY!!!!
