So I really want to buy my friend's iPhone 3G for $250 because she doesn't want hers and doesn't like it for some reason. I don't currently have the money to pay for the plan so I was going to use it as an iPod Touch until I saved up some money, and this will probably take me about 6 months. Although I'm gravely disappointed and upset, a lot of people have been telling me that the iPhone 3G locks up once the contract is canceled; I've also heard there is a short period of time instead of it doing it right away. But there have also been a few people telling me if this is crap and that if you're told this by Apple or AT&T then they're just trying to scare you. So what do you guys know? What is true here? And I would love it if you posted some links. NOTES: 1) I posted a thread a little like this but at that time I just wanted to find out if it would be worth it. 2) Don't tell me to use the search to find my answers, I tried that. 3) I have a tendency to not trust Wikipedia but I will still take a look at it.
