I have a new Verizon 4S that I got thanks to my neighbor. She was going to renew her contract with a regular flip-phone so I got her a new flip-phone on Ebay and she renewed her contract and I got the upgrade, a white 16GB iPhone 4S. I've been looking at prepaid plans on Verizon and the best I could come up with was Straight Talk. $45 for unlimited everything is hard to beat. Can a Verizon iPhone be used on Straight Talk? If anyone has used a iPhone 4 I'll try to use the iP4S.
