Hi So i upgraded to 3.0 GM and when I went to tethering it tells me I have to check the o2 website for details on how to update for tethering. This is a bolt on that they are providing for a rdiculous price I think we all agree So i tried the old o2_uk.ipcc file and updated my carrier settings. Tethering now works perfectly My question is, does o2 know I am tethering in any way or am I "tricking the system"? also, can this method be retro disabled by simply syncing with itunes? or am I safe til I update the software or restore? any thoughts on this?
