I've been using a 2G iPhone since Sept. '07, and am thinking of upgrading to the 3G. I'd really like to stay on GoPhone, rather than sign a contract for 2 years. I just don't trust AT&T to make it that long without making me want to switch. The 3G recently changed to a "home activation", can I get one, stick my 2G SIM in, and be good to go? Anyone tried this? Anyone purchased one from AT&T online, and done the home activation? Did you have to sign up for a contract before your iphone arrived? How does that work? According to quite a few sources, my curent SIM will work in a 3G. Does it have to be unlocked first? I've heard the Dev Team is releasing a 3G unlock in January, what do I need to know? Or am I looking at Ebay or Craigslist?
