When Apple finally sells the officially unlocked version in stores, will it be one device that will work across all of the U.S. carriers? Or will it be GSM or CDMA like the 4S? The reason I'm asking is because my wife will let me buy an iPhone 5 at full price, with the intention of switching to T-Mobile once their 3G coverage supports the iPhone in our area. Rather than waiting for that to happen to get the iPhone 5 I was thinking that I would buy one and use it with my Verizon unlimited plan in the meantime. So I was hoping that when they do release it that I would be able to bring my "Verizon" iPhone 5 over to T-Mobile without having to get another device. The only downside to this that I can see would be missing the LTE data speeds. We're definitely switching to T-Mobile though since our monthly bill will be about $60 cheaper per month.
