If your iPhone has version 1.1.2 on it out of the box you won't being doing much until 1.1.2 is jailbroken. iPhone can be downgraded to 1.1.1 so you can mod them, but I think if it comes out of the box with 1.1.2 already on it you are SOL.
Sweet! It left FT WORTH, Texas, at 10:02pm on the 10th! I hope it arrives here tomorrow like it says it will. To tell you the truth I saw some fedex trucks and my heart was running! I'm so excited that this year I got to treat myself to something, and still have money left for friends and family.
One more question lol. What is "roaming"? I understand you can rack up a HUGE phone bill because of it. Consider this scenario, I live in Alabama, and I am going to go see my mom in Michigan. Is that considered ROAMING?
