According to Boy Genius Report, Apple is testing an iPhone model for the T-mobile network. As shown on the picture, the iPhone indeed does look like it works on the T-Mobile network. Of course, if the AT&T acquisition does get passed, T-Mobile customers will get access to the iPhone either way.
Still, if consumers can their hands on the shiny apple device sooner, I’m sure they wouldn’t hesitate to make the leap! The white iPhone seems to have a model number labeled N94. The model that run’s on Verizon’s CDMA network is called N92, while the AT&T model number is N90. The device is also shown running what seems to be the next version of iOS. There are some noted differences however, such as the unique proximity sensor shown on this T-Mobile version.
