Hi, this might be a dumb question to you in the states, but I'll be back in the states for 6 months and don't want to get stuck in this stupid 2-year contract thing. I am bringing my unlocked iPhone 3G and am wondering...is there a company I can buy a prepaid SIM card and use in my iPhone for a few months? I know a website "www.mrsimcard.com" sells one, though I think it is a ripoff. $80 for a SIM that I have to buy credit for? Is that a good price? I paid $10 for mine. I have a SIM card now, but I'm quite sure it won't work in the states, and I wouldn't want to with roaming. What do people with bad credit do in the states, those who are unable to pass the credit check?
