I have a few questions about the Xperia Play... If you buy it online, and use your current Sim Card, do you still have to pay for a Data Plan? Could you unlock it, as in using different carriers, like T-Mobile? I read somewhere that you can access the Playstation Store so that you could buy/download more games. If so, could you play downloaded PSP ISOs/Games? Where is the cheapest place to buy the Xperia Play (besides bidding websites)? That's all for now, I might have more later.
