My family has T-Mobile and my phone current phone is dying on me. I really want the Xperia Play but I know it isn't through my provider. I realize that I'll have to get an unlocked phone. Here's my list of questions: 1. Anyone here using an unlocked phone? What are the pros and cons. 2. Anyone here using the xperia on T-mobile? Any noticible differences in usability? 3. What are my best options for purchasing an unlocked phone? Pre-unlocked, AT&T version, calling AT&t and getting it unlocked, unlocking code, etc. I've really resisted the touch-screen revolution and I figure if I have to give in I should get the phone I want. ANY tips or advice is greatly appreciated, including basic Android info. Thanks Again.
