Okay so I've done some research and this is supposedly how GoPhone on iPhone 4 will work. 1. Buy new iPhone 4 on eBay or at the Apple Store. 2. Buy AT&T 3G prepaid sim card on eBay. 3. Activate sim online or call the people and enter the iPhone's mei thing? (haha i pretty much have no idea what that is) 4. Set up prepaid plan. 5. Cut sim card so it will fit in the iPhone. 6. Put in iPhone and add airtime credit. Are these steps correct? Do I need to jailbreak or anything? It would really help if someone cleared some things up. Thanks!
