Can you use Verizon's iphone 5 on Virgin Mobile's Network?

If this is a stupid question please forgive me, I'm not a tech guy like that, but I do know that Verizon Wireless' iPhone5 came Factory Unlocked. I asked the rep that sold it to me at Verizon. My contract with verizon wireless is about to be over soon and i'm looking for something a little cheaper. So i thought,"why not virgin mobile" Some people have told me that i can, others told me no i can't. Can someone please let me know if this can be done or not. I want to use my Verizon Wireless (which comes factory unlocked by default) on virgin mobiles net work

How long can i use the internet for if i only have 250MB?

I've just been given a new contract. I'm just wondering how long i can spend on the internet a day with 250MB? I also have another question. I have an iphone and if you press the home button twice it comes up with all the apps that are still running. Does this mean its using up all my mega bites (MB) still or is it just there to drain your battery?

Can I buy an iPhone from Apple and use it with Sprint's No Contract plan?

Here's the deal:

Sprint.com offers a refurbished iPhone 4 8 GB for their No Contract plan. I want a NEW phone (a 4S preferably), in case of something going wrong I know it's my fault and not the pre-owned phone.

Apple.com is offering the 4S (with Sprint as the carrier) for the same price as Sprint if you bought the phone with a 2-year contract.

And so, can I buy the phone through Apple and use it with Sprint's No Contract plan?
