HTC TyTN

I've had the Cingular/AT&T Wireless 8525 version of the HTC TyTN PDA for 18 months now. It's been a very reliable phone with good call quality, a nice loud speakerphone, decent screen display, and excellent flexibility in using not only Windows Mobile apps but a number of my old Palm OS apps as well via the StyleTap compatibility application.  I like the voice dialing capability too. Upgrading my browser to the beta version of Skyfire has enabled me to have an iPhone-like display while surfing the net.
After upgrading from WM 5 to WM 6, the phone became a lot more stable and almost never crashes anymore. The only irritations in using this phone are these two:  1) the PTT talk button on the side is too easy to press accidentally (and you can't disable it); 2) trying to dial usually requires the use of the stylus unless you're sitting still and concentrating on where the virtual buttons are on the display.
This was my first HTC phone and I have to say that I'm a fan of theirs now. For anyone who uses some version of this phone, you can look forward to the new HTC Touch Pro which will replace both this phone and the AT&T Tilt (TyTN II) when it's released on October 23, 2008. AT&T's version will be called the AT&T Fuze and will employ the TouchFlo technology which uses an accelerometer like that in the iPhone to change the display orientation when the handset is rotated.
All in all, this phone has been outstanding and I'd give it an 8.8 on a scale of 10.

this phone is able to use the micro sdhc cards. they show that it doesnt and people just assume it cant, but i have an 8gb card in mine right now and it works perfectly

I like change my mobile often. This is the fourth windows mobile that I have. But this is my partner since 1 year and a half ago. And in facts, I'm happy. We could say that has a big size and a its battery is not spectacular. But now, that I'm thinking to change it ( most because I'm bored of see it every day) I don't see any machine that represents a big change for me. With the same features, more or less, the same battery and the same size, I think that the market can't offer to me a representative change. This could tell me two things: 1. The market didn't do anything, 2. This machine really is good.
I have changed the operating system to newers version of windows mobile. But , I didn't do nothing more to the machine. Really, this phone was a good piece of what HTC can do. It's hard and usable. Good connectivity.
