Haven't had any problem between my AT&T-branded Pre3 running freeTether and my TouchPad. It's worked well on Bell Canada and now while I roam on Globe Telecoms in the Philippines. Pre3 is running v2.2.4 webOS and TP is at 3.0.4. Connection has always been stable. Ping times to my Pre3 has always been quick. Only issues I've had are the slow network connections through Globe Telecoms, but that's not surprising.
