Killer Combo: iPhone 3G and GoPhone
That was easy. Take an activated AT&T GoPhone, an inactivated iPhone 3G, swap SIM cards, and now I got a working iPhone without a long term service contract.
If you want more details, especially on enabling a GoPhone data plan, be sure to read this post, How to: Give Your Old iPhone New Life With Prepaid Data and Minutes. But if all you want is basic voice calls then swapping SIMs is all you need to do. The hardest part might be ejecting the iPhone 3G SIM card. The iPhone 3G came with a special tool for SIM removal but a pushpin or paperclip works too.
There’s no need to jailbreak your iPhone either. Because I didn’t need data or want to pay for a GoPhone data plan, the iPhone can’t connect to the 3G network, but WiFi is still an option. And of course, all other iPhone functions work as normal like syncing with your Mac.
