not sure about wireless tethering without root. but yes, try fresh's rom, or any custom rom really. it's pretty easy (I was always scared to root and try roms on WinMo, but it's so easy on Android that I had to try)

also, you'll see a pretty noticable difference in the way the phone works. it's amazing what these guys can do with these phones. makes me wonder wtf the actual android developers are getting paid for. these guys just come in and fix everything they screwed up.
