Virgin Mobile on a used Iphone?

I have an older Samsung Intercept with Virgin Mobile's 25/month plan (i'm grandfathered in). I really like it; 300min, unlimited texting and data. Its great because every other smartphone plan seems to be way more money.

I'm looking at picking up an iphone, for the apps and speed. Virgin mobile sells the Iphone 4s for $650, which is way too rich for me.

My question is could I buy a used iphone 4s, and switch my plan to avoid having to buy a brand new expensive one?
Would I be able to keep my 25/month plan as well?

Is 1GB Enough data for iphone 4s verizon?

I will be the only one on the plan, I will surf facebook and twitter multiple times throughout the day, and It will be connected to Wi-Fi when I'm at home. I'm not gonna stream music from it, because I already have a 32gb ipod touch for entertainment purposes. I'm just wanting the iphone for calling, texting, social networking and a few games.

Which iPhone 5 case/ screen protector?

I'm looking at the Otterbox defender series vs. The commuter series. I like the defender because I really like the look and protection. I don't like it because it has its own screen protector which I heard wasn't the best and it is bulkier and can't be slid into a pocket easy because of the rubber casing. I like the commuter because it can be slid into a pocket easy, doesn't come with an attatched screen protector, and still has good protection. For a screen protector, I would like ZAGG Invisible Shield, but they have a choice between Hi-Definition, EXTREME, Original, or Smudge Proof. I need help choosing which case and which screen protector I should get. If I get the defender, could i cut that one out and put a ZAGG on it?
