If i buy a used iphone 4s can i activate it with verizon's prepaid plans?

I'm a minor so i can't get a contract on my own, so i figured that a prepaid plan is the best option for me. Is there any sort of deposit or contract or credit check or anything like that? And is it one of those prepaid plans that you get on a card from walmart or something?

No. Verizon will not activate a Iphone with prepaid service.

Of course, you an go prepaid. Go for StraightTalk, buy a prepaid SIM from them at WalMart and put it in your iPhone 4S. But before you do that, you need to unlock your iPhone. You can mail this person (arghyle@rocketmail.com) who can help you get the phone factory unlocked.
