Re: how about a reference?
I don't know what kind of reference you want, but I have been fighting this for a week now and I can assure you it is very real and a major pain in my ass. Thankfully for laptop users it has not cost me anything as I have enough padding in my shared data to absorb the added usage, but a lot of consumers are going to get a surprise on their next cell phone bill when they find they inadvertently used 3+gb of bandwidth with their hotspot/tether.
