I'm not yet a T-Mobile customer, but I'd like to be...
I have an iPhone 5 with Sprint service. It is "unlocked" for international usage, and I'm aware of contractual requirements to pay an ETF. I did use it for international usage and still have British and French nano SIM cards. Ironically, when I have these SIMs installed in my phone while back in the USA, I can "roam" on both the Three and the Orange networks (international providers), and I can SELECT T-mobile as my provider. When I install a T-mobile SIM, I get shut down. Locked to Sprint.
Apparently, the Sprint iPhone 5 is not like the AT&T or Verizon versions that come "factory unlocked" for migration to other providers. However, on the T-mobile homepage, the option is given to select your own device that you are bringing over to T-mobile service. The iPhone 5 for Sprint is approved as one of these such devices.
a) How can this be done?
b) Please update your webpage and remove this device, as it provides false hope to Sprint iPhone customers looking to transfer service!!

I see what you are saying, but I do not see the fault with T-Mobile in this. If you are going by compatibility, the sprint iphone 5 CAN be used on tmobiles network and tmobile is has the right to say that on their website. It is SPRINTS fault that it is locked for USA carriers. However, some people have found a way to force the unlock to make the phone work on tmobile either by jailbreaking or by using an R-Sim (search it on google).
