Rumors have been circulating the past few days that Nokia would be teaming up with T-Mobile to release the Symbian^3-powered C7 -- right on the heels of the Nuron 2's possible cancellation -- as the Tiger. Well, here's some fuel for the fire: a version of the C7 with AWS 3G support and mentions of T-Mobile in the attached user's manual just showed up in the FCC. Interestingly, there's absolutely no sign of T-Mobile branding on the phone itself, but it's possible Nokia's prototype here simply didn't have the final silkscreens applied. Of course, plenty of devices get FCC approval without ever seeing the light of day -- but it's a sign. Who's buying?
