T-Mobile has now officially gained the Nokia 7510 but with less of the Supernova branding for some reason, one can only guess why T-Mobile would drop the name as it sort of places what would normally be an interesting mobile phone into the realms of the anonymous.
The T-Mobile Nokia 7510 supports Wifi and thus is probably one of the better HotSpot enables mobile phones out there.
Feature wise the T-Mobile Nokia 7510 handset offers a translucent covered OLED QVGA display, 2 megapixel camera, myFaves support and Bluetooth. The T-Mobile Nokia 7510 also has interchangeable face plates in Emerald Green, Expresso Brown and Fatal Red, and should be available in a few weeks.
