Hi, this is my first post here. I'm thinking about buying an Iphone, unlocking it and using my current o2 'online 30' sim card. I'm very wary of unlocking it myself so I'm going to be using iphoneunlockuk.com. I know there are mixed views on the service that these guys offer but I'm the sort of guy who needs peace of mind that I will have a real person to talk to if things go wrong. The only thing at the moment which is stopping me is EDGE. I do not want to access the internet using this service, I'm a poor student who can't afford the bolt on from o2 This means I only want to access internet, email, you tube etc using only WIFI. I have done countless searches on this topic but the ones available are either old [concerning previous updates], US Iphone or other UK network providers. So, is it possible to disable the EDGE function, and how is it done? Thank you very much for reading this, sorry if this is a nuisance question with an easy answer.
