White iPhone 4 with T-Mobile USA 3G support spotted

BGR.com has posted photos of what appears to be a prototype white Apple iPhone 4 with T-Mobile USA 3G support, as noted by the "T-Mobile" and "3G" text at the top of the phone's display. BGR notes that the front face of the device appears to have been tweaked a bit from earlier white prototypes. BGR suggests that this could just be a test device that would allow Apple to test compatibility with T-Mobile 3G bands for some future model, due to it being so late in the iPhone 4's life cycle. We would add that Apple could choose to offer an older iPhone 4-based model to T-Mobile once a newer iPhone 4s/5 model was made available to AT&T and Verizon.
