I had the iphone 4s for like six days and hated it. I'm not even sure why, but it felt like a toy to me. I returned it and got the S3. This has probably been about a year ago, maybe. It's by far my favorite phone I've had. The iphone is popular enough though that it must be cool and I'm just a flake. If you've already had an iphone and like(d) it, you probably can't go wrong either way.
