Ok, so I narrowed it down to either the AT&T Tilt, Verizon Voyager or the Iphone. Anybody use the Voyager? Looks similiar to the Iphone only with 3G speed. How the web pages look on it? How well does it work for e - m a i l?
Depends on what you are doing with it.
If you are doing REAL business with your device you want the HTC TyTN [ATT-8525] . If you are doing REAL business and want a slightly faster processor, more memory and GPS means anything to you than get the HTC Tilt [also known as the TyTN II].
I've been using an 8525 for 14 months. I just upgraded to the Tilt, because the GPS works great with Windows Live Search Mobile, and I will actually use it as I am on the road a lot. The faster processer [they are both 400mhz, but the Tilt sports a dual core chip from a different manufacturer than the 8525 and runs a bit faster] and extra memory are nice to have as well.
The Tilt sports a 3Mpix camera that is better than the one on the 8525 as well, if that means anything [not important to me] and can be set to use as a mobile webcam if needed.
If you get the Tilt add the Spb Software's "Pocket Plus" [latest version is 4.02]. It truly adds to the functionality of any Mobile PC Smartphone or PDA. You won't need Voice Commander 1.6, as you would with the 8525, as it is built into Windows Mobile PC ver. 6.
Hope that helps.
