Mine is a company phone. I generally get the "next great thing" when it comes out. I've been looking at the S3 with some desire. Maybe, maybe not. We'll see.
My biggest requirement is to keep unlimited data. The guy on my staff that works with our Verizon rep is a miracle worker and he assures me that I'll be able to switch phones and retain my unlimited plan even after the end of June. If so, I may be looking at the S3.
We always have over 70 phones that have renewal availability so I could change phones weekly if I needed to. Upgrading isn't an issue, it's the sleight of hand needed to keep unlimited data.
