Is the Verizon iPhone 5 compatible with Tmobile's 4G thats rolling out throughout 2013? Or do you have to have an unlocked ATT version to support it? Or does neither support it?
That's not true sir. The 5 will work as the Verizon is factory unlocked. I could pop in a tmobile sim right now and use their network. As far as 4g yes that will depend on tmobile and what freq they choose to use. Now that I think about it the Verizon 4s will also work on tmobile if its unlocked as its also a world phone.
