HTC Titan is approved for the States1
The FCC documents show images of the Design versions of the Titan, just as the Wizard (the GSM cousin of the Apache) has two versions – the one was carried by T-Mobile and the other by Cingular.
The Titan upgrades the Apache with internal antenna, 2-megapixel camera, EV-DO Rev. A and probably WM6 Professional OS.
