A bunch of photos surfaced recently by BGR shows an unreleased white iPhone 4 device running on T-Mobile USA network. It looks like an iPhone 4, although, the proximity sensor looks different than the one shown in the final white iPhone 4 that’s been already sold in the UK. The device is running an old and internal test version of iOS 4, confirmed by the several Apple internal and field-testing applications like Radar and Apple Connect or the preference panels to measure the performances of the device.
That’s right, you’re looking at photos of an iPhone prototype with T-Mobile USA 3G bands. The actual internal model is N94, and if you remember, the Verizon model is N92 while the standard GSM variant is N90. We have verified that the phone itself is running a test version of Apple’s iOS, much like the one we saw in those videos from Vietnam, and it includes internal Apple test apps like Radar and Apple’s employee directory app. Additionally, the front of the white iPhone pictured looks a little different from the photos of the retail white iPhone 4 that surfaced recently — specifically, the proximity sensor has changed on the retail version.
The model number of this iPhone 4 is N94, its related to the A5 chip — which is implemented on the iPad 2. Remember that there is the prototype iPhone with an A5 processor that game developers are using to prepare their iPhone 5 apps. That sounds a lot like this phone. The only question now is if that is a prototype ’4S’ or ’5′.
