The reason I ask is, vodafone (my UK network) had this stupid content control on which blocks going to websites like flickr and some iphone forums for some reason, i've just called them and had it removed but it made me wonder if they could therefore see what sites I go on etc, so if I was to jailbreak it or something would they be able to see i'd been to jailbreakme.com and therefore know my warranty is effectively void?
