I have an iPhone 2G currently and plan on moving up to the rumored, new iPhone. I want to give it away to another family member, which is on the same family plan, but do not want to add on another data plan as it is not needed for them. So, what are my options? I am thinking of doing a quickpwn unlock on it but was a little worried about a couple things. Firstly, how do I turn off data on it? I have an unlimited messaging family plan so I don't know if I can ask for data to be turned off completely on that number. Secondly, is it possible for ATT to know that I am using an iPhone on the number and either charge me the data plan, or do something to that number (such as an overage charge or disconnecting the number)? I may just be somewhat paranoid here but the whole point of me doing this is to save money by not adding another data plan. Thanks for the help. For those who don't like reading... I have iPhone 2G that needs to be unlocked for ATT (Currently on ATT). How do I cancel data while keeping family text plan? Any way of being charged extra on my bill?
