The Nokia Lumia 900 is currently an exclusive to AT&T, but earlier rumors this year suggested that AT&T would only be getting the exclusive for 45 days before the handset makes its way onto other carriers. Assuming the T-Mobile store rep that spoke to Andrew Bares at WMPoweruser is to be believed, it looks like T-Mobile could very well be getting the Nokia Lumia 900 this summer. However if that were the case, LTE would obviously be a no-go for T-Mobile subscribers as the carrier has yet to get its LTE network up and running. Also for those who might remember, the earlier rumors have also suggested that non-AT&T versions of the device could also see a 12MP camera which will be an upgrade over the current 8MP. We will be taking this information with a grain of salt for now, but are any T-Mobile subscribers out there possibly looking forward to getting their hands on the Nokia Lumia 900? Perhaps the magenta-colored Nokia Lumia 900 spotted at a Microsoft store could be an indication of what’s to come.
