Windows Mobile 7
From everything I've read (and everything you could
have looked up yourself), nothing works on a Wizard as well as Windows. Many come close
to working, but unless you like crippled devices, I'd stick to Windows. There are some really nice cooked Windows Mobile 6.1 based ROMS in the Wizard Mobile 6
I know you're new to these boards, and I was a noob once, too, but please use the search engines, and do some research on your own. Not everyone will be nice about this.
