How to switch a iphone 4 on verizon over to my own account?

The person I got it from still has it activated in his name. But there's no way I can get him to take his name off. Is there anyway I can reactivate it into my own account?

Give him a call!

Yes. Call Verison or visit one of their stores.

I have to assume you're asking us because it's stolen and you can't simply call the company. In which case it's an iPhone and you might as well have stolen a rock and tried to activate it as your new phone.

If you called Verizon and Verizon can't help you, then no one else can, LOL. Sounds like a stolen phone, if the seller won't help you.
