I just got something from my US colleagues and the current plan is to have an “a”-variant available at retailers this summer. This version will be optimized for use in the US (GSM/UMTS). I’ll keep you posted as I get more details.
So it’s coming this summer, right? It will be available on retailers (looks like BestBuy to me) and maybe on mobile carriers. As it’s coming in a GSM version, the device might hit AT&T or T-Mobile. My guess is that it will hit AT&T, as they are already offering the predecessor of the device Xperia X10.
So Arc fans in USA, the device is headed to USA so start saving money if you are looking forward to this device because it’s going to cost you a lot of money.
