The rumors that T-Mobile may launch a Google Android device in September seem more and more plausible now with the details that Engadget found in the latest FCC documents (PDF files). This FCC approval is for the rumored HTC Dream device. The operating system is not mentioned in the FCC documents so it is possible this device could be a Windows Mobile device too. Either way, it looks like this may be T-Mobile USA's first high end device that supports their 1700 MHz 3G network. The FCC documents reveal it has WiFi, Bluetooth, and T-Mobile 3G support.
In other possible T-Mobile 3G news, it looks like the Samsung T919 (aka Tocco) may be coming soon. I haven't use a feature phone in some time, but this looks like the T-Mobile answer to the Sprint Samsung Instinct device and if you want an iPhone alternative with T-Mobile 3G support this device may be just the ticket. This may also be the one feature phone I actually do pick up from T-Mobile and I'll be keeping my eye on the release of this device. The Samsung T919 has a 5 megapixel camera, integrated GPS, microSD card slot, and full touch screen display.
