Can i use an unlocked iphone without a data plan (sprint)?

If i get an unlocked and/or jailbroken iphone, can i activate it on the sprint network without having to upgrade my plan? I currently don't have data, and i don't want a data plan, but sprint won't let me purchase an iphone through them without getting a data plan. And if i activate the phone on the network, it will sense that it is an iPhone and automatically upgrade my plan.

so, if i buy an unlocked and/or jail broken iPhone, would i be able to activate it without Sprint recognizing it?

Probably, my friend did it with i think at&t and it worked for him. It should work considering sprint and at&t have similar plans available

DO NOT DO IT
You should have a data plan to download and connect with intenet and nave more
