I passed on my original iPhone to my Mum when I upgraded earlier this year. She has been using it with an O2 iPhone PAYG sim but doesn't really make calls or texts as she has another phone on contract to do that with. What she does do, however, is access the internet via our own home's WiFi. Originally she had O2's web and WiFi bolt on (at £7.50 a month) but dropped this after about two months as she realised the only real time she was using the internet was at home, when it would be free anyway. However, O2 now insist that this isn't free at all - despite the fact we own both the WiFi network and the iPhone - and are charging her some sort of rate to access our own wireless network. Is this right? They say that it is a ruling imposed by Apple, not O2, interestingly. All data roaming is turned off so there is no chance that she is ever using the internet anywhere or anytime other than where/when she thinks she is - i.e. in the home.
