I've been usingwireless tether for the better part of 6 months..average usage 30-40 gigs/month...home pc, 3 ipod touches..etc...and have never had any issues(Knock on wood). Ive.been running CM7 using barnacle wifi tether with almost 100% problem free usage...I just flashed CM9...built in teher will not work...nor will barnacle...so i found one call "open garden"....Any questions ...just ask.
