Hey!! Thanks for the IM. Of course you would message me about tethering which I don't use;-) I did attempt to tether my 101 to my iPhone and was not able to. I would also add that I tried to connect to other cell phones via bluetooth and could not get that to work either. The other phones were none iPhone devices. It would seem to me that apple products have a tendency to not play well with others. I have a BlackJack II that seems to work just fine with 101. DO you have another phone you could test with other than the iPhone?
