I have a Verizon iPhone and I want to hook it up with Straight Talk. Can anyone help me?
Your iphone has to be unlocked by Verizon.
Pending your contract they might or might no do that.
After that there is no problem using Straight talk.
I use my iPhone from Verizon (not unlocked by Verizon) in Thailand, where they don't provide any kind of Straight talk.
So IMO, to not use Verizon services with Verizon iPhone - this would be one option to do so...
