Well I got a chance to ask, "if I had to do it all over again, would I do it the same?" and the answer is YES!
I have a white S3 that is basically 2 months old and a network issue. Due to a silly customer care person, that refused to listen and file a network ticket before they switched my phone out, I'm on my FOURTH S3 in less than 2 months. My phone was fine and every warranty phone they have given me has had an issue, even though they were never activated phones.
Tonight when I threatened to yank my service, when they wanted me to go back to the Warranty Store, they got me to retention and they are sending me a new in the box, brand new complete order for free. He asked me if I wanted a different color this time or wanted to stay with the white. Didn't even have to think about it, I love that clean look of the white and it goes great with my pink Ballistic case with the white corners.
I have a Commuter case by Otterbox, but it was just too bulky for me, so I got the Ballistic that doesn't offer as much protection, but offers some and keeps my phone with that slim feel.
