I have been a T-Mobile USA customer for several years now and one of my favorite Pocket PC Phone Edition devices was the current T-Mobile MDA/HTC Wizard. I did eventually give up on the device though since the processor was just a bit too slow for handling the heavy tasks I threw at it. I just read on the Phone Scoop site that FCC documents revealed the next upgrade to the T-Mobile MDA. The HTC Herald/P4350 offers several improvements, including a nicer form factor with the casing similar to the T-Mobile Dash, 2 megapixel camera, Windows Mobile 6 operating system, BT, WiFi, and quad-band GSM/EDGE (no 3G since T-Mobile USA hasn't rolled it out yet). Specs for other HTC Herald models include an OMAP 850 201MHz processor, which is the same as in the Wizard/MDA and I hope Windows Mobile 6 helps out with the processor capability and functionality. There is no word on pricing or availability yet, but the current MDA is definitely getting long in the touch and is ready for an upgrade.
