HTC's successor to the TyTN/8525 line of smartphones isn't quite out yet, but it has been photographed. Featuring Windows Mobile 6, HSDPA, a 3-megapixel camera, and GPS, this phone actually slides the opposite way as previous ones. Plus, there's a caps and function light there to signal whether it's toggled. Very useful.
No word on when/where this will be released, but the FCC says Verizon or Sprint.
