Our guesses for 'Project Charlie'

So three mysterious AT&T devices bound for AT&T have appeared in Best Buy's computer system. They're dubbed "Project Charlie," and that's all we know.

Is it possibly they're Windows Mobile phones? Sure. We're expecting new stuff from HTC — the Touch Diamond 2, Touch Pro 2 and the Snap — in the coming months. But HTC stuff generally doesn't get cloaked in that much secrecy.

The Phone Arena tipster thinks it could be placeholders for a possible upcoming iPhone, and that's probably a good guess. Us? We're hoping for a personally branded phone from one of our favorite Charlies.
