I am going to sell my touch and buy an iPhone. I live in Canada so I'll unlock it and use it on Fido and will most likely be using pay as you go. OK, so is there a way to turn off ALL of the data while on EDGE? Data costs are insane in Canada and I don't want a $200+ bill. However, I would still like to be able to use sms. Then, while at home, I would use my Wi-Fi for internet, email, TTR, etc. Is what I am asking doable?
