Just a quick note: If you use a T-Mobile Dash you should head over to the T-Mobile WM Upgrade page and download the free Windows Mobile 6 package. While it doesn’t fix all of WinMo’s issues (it’s still Windows), it goes a long way to make it more usable and intuitive. And it’s free. We like free.
Make sure to do a sync and a complete back up of your Dash, because the upgrade is gonna wipe everything out. You’ll lose your Yahtzee! scores. We know, we feel the pain.
