Just wanted to say I got the SetCPU installed - installed the 900 kernal and am currently running 800 max 500 min - no problems yet.
Temp says 111.2F and the phone is noticeably faster. So far haven't had any problems opening movies, pix, camera, phone, etc.
Another quick update. Phone is working GREAT! Still running at 800 max but that seems to be just fine - the phone is super responsive.
Tried out the wifi tethering with my wife's Ipod Touch - works GREAT.
Thanks to this forum and to all who help out with posts and how-to guides - you guys are fantastic!
