After revealing HTC’s Fiesta for AT&T, today we have seen a reliable document that lists yet another Android phone but this time headed for T-Mobile. The document lists the device name as T-Mobile Opal, which also happens to be the codename of the HTC Touch Viva, announced last year. Unfortunately, we do not have any pics or juicy specifications to go along with this breaking leak, but if it is just an Android version of the Touch Viva, you’d probably facing a cheap Android phone with a 2.0 MP shooter, a 2.8 inch QVGA display, 256 MB ROM/128 MB RAM and Wi-Fi connectivity.
