Hi, Can someone please explain to me everything that is involved with using a 1st generation iPhone on T-Mobile? Specific questions: 1-I know I will need to jailbreak it and it will only run on Edge. What plan would I need to get with T-mobile? I have read about $5.99 T-zones, and $19.99 and $29.99 plans. 2-Would I need to get a T-mobile phone and pull the SIM out and then place it in the iPhone? 3-Could I do a Pay-as-you go sort of thing? 4-Can I get data only, I don't really need voice. Thanks!
