In other news, GiffGaff have started enforcing the "no tethering" rules, my lodger is distraught, he has been running his thriving internet business off of a £10 a month goody bag for a couple of years, downloading ~ 100Gb per month of films to watch as well!!
OMG 100GB (I assume you meant GB not Gb?) off a mobile broadband connection? Well no wonder they're clamping down as that's going to cost them a bomb. Mobile capacity is much more expensive than fixed line.
