OK - let me preface this by saying that I know that its not currently possible to unlock a 3G iPhone - which is sorta why I'm asking this question.. I'm not sure of the terminology. I currently have a 1st Generation iPhone which I am using with a Pre-Paid card through AT&T - I have a legit pre-paid account and each month I apply $20 for unlimited data and $5.00 for 200 texts.. It seems to work fine for me since I don't need voice (I have Verizon for that). Is this possible to do with a 3G? Since I'm using AT&T as my carrier I'm not really unlocking anything, am I? I'm not sure if the jailbreak process allows me to do this, or the unlock, or just the activate (I've been using the iPhone-Dev Pwnage Tool since it was released for 2.0.x). Just curious - I'm not really ready to spring for what a 3G would cost without a contract but had been curious in case I came across a good deal..
