Hmm, I must investigate. I was using my Android phone and tethering with my laptop a couple of weeks ago.
Didn't think anything of it since I have 500MB of data in my TalkMobile contract. Don't use anywhere near that, but after reading this I shot off to check my terms and conditions. Didn't see anything about tethering, just about using it for illegal content.
Hope facebook, gmail, yahoo mail and some facebook apps and games don't falll into the category of "illegal" material
Well, we shall see. Not had any emails or calls about it so have to assume it's ok?
