Currently, I have an iPhone 3GS and the $30 data plan, and my parents just have regular phones and no data (because they don't need it). Today, I bought my dad an iPhone 2G 8GB for $130 (with phone, case, charger, dock, cable, and headphones -- sweet deal!). Anyway, I have some questions about him being able to use his new iPhone. 1. Will disabling "Edge" through SBSettings ensure, 100%, that my father will not be able to use data no matter what? So no surprise charges? 2. Can AT&T find out my father is using an iPhone instead of his old LG phone and MAKE him use the data plan? (Note I will disable data) 3. I plan on jailbreaking, and because unlocking is very easy with redsn0w and iPhone 2G, I plan on unlocking too (even though he will continue to use AT&T). Will unlocking have any adverse effects on the iPhone 2G? (because I can remove it I think, considering we are on AT&T). 4. Since the iPhone 2G isn't the phone my dad is supposed to be using, and because he doesn't have data, will he see any dropped calls or anything like that? Without data and the iPhone being the official phone, will he suffer from any problems on the iPhone? (The reason I ask is because my friend, who is using a 3G instead of his "real" Sony Ericcson phone", does not have data, and claims to be getting calls not going through or calls not being received. I want to know if this is true). Lastly, I want to know if there is anything I should worry about, but I think I covered it with my questions. Thank you very much guys, I just want to be thorough so I don't encounter any problems or "surprise" charges. Thanks a lot and please answer ALL of the questions!!

I unlocked it and everything, and when I check the AT&T website, they saw my dad's phone as the iPhone instead of the LG phone he used to have. I *think* I have successfully disabled data by turning off Edge in SBSettings, but why does AT&T still see my dad's phone as the iPhone?? How do they know? Is this a problem? ie. Will they force him to get data? I have changed it back to the LG phone, but I dont know if it will go back to the iPhone later on.. Also, why does AT&T say I am using an iPhone 3G when I am using a 3GS..? Does this make a difference?
