Just picked up my S3 (AT&T) yesterday. I am a longtime iPhone user, but I recently sold my 4S, then used a GNex (Play Store) for a month. The plan was to "mess around with Android while I waited for the iPhone 5." But... Jellybean had me so impressed that I have decided to stay... so I used my upgrade on a red Galaxy S3!
Mac and Android user. Can't we all just get along?
