Well I better start a list for my phone as it is very long

I got the AT&T Tilt even they dont sell it anymore I still believe its the best phone ever made still.

It is a Windows Mobile phone so it does a lot. Every program you could imagine is free on Windows Mobile phones.
I have:
Microsoft Office Mobile on my phone to type up reports, graphs, powerpoint presentations. Im a college kid and I dont always have a laptop on me.
I have gps program on it that gives me full features even with turn by turn speech for free as it has built in gps.
I can connect my phone to my laptop through a usb cable and connect my laptop to the internet if no wireless is available.
The obvious youtube.
Email.
Text messaging.
Free music ID program.
Check weather.
Microsoft released mobile bing to check movie times, gas prices, etc in the area and can double as a gps but I have a better program.
It has full internet access with internet explorer but I may try mobile firefox soon.
I keep things to do on a calender on it.
It has windows media player so it has music as well.
There are countless downloads that I can also get on just one website alone that makes thousands of programs for windows mobile phones. The only thing I wish I could find is a program where I can make speech to text for text messaging without having to use the keyboard or touch screen to text.
