Well, a week after installing WM5 it finally killed my Axim. After installing WM5 I had to do a soft reset most times just to get it to turn on. It was really slow but usable. The only benefit I could see was that my BT connection finally worked.
Last night I went to reinstall 2003SE and there was no power at all. It obviously turned on and the battery ran out as I had just charged it. I charged it and now it hangs on the 'Dell' blue screen. I have done multiple soft resets, hard resets, and pulled the battery and nothing works. I can't even turn it off now.

I am on hold with Dell right now to get a replacement.
So sad....
