Best Company to get Iphone contract with?

I want to get an iphone, but i'm a student on a budget. I want to know which company (AT&T, Verizon, T-mobile, MetroPS.) has the best contract deals. I want facts, like monthly payment, internet, minutes, texting. Thank you!
P.S- my sister got the iphone 4 last year with AT&T with limited internet, and she pays $90 a month. Are there newer deals now?

IPhone 4 screen was acting weird?

I just got a used iPhone 4 from eBay and it worked perfectly when I first got it. Then, after about 10 minutes of use, I was scrolling on the Settings page and it started getting all shaky and tapping in random places. I went back to the home page and tried the Phone app. I would tap on number and it would then tap like 10 other random numbers at once.

I restored it, then it worked perfectly again. It has yet to do anything weird. What happened? Is it a bad digitizer? Bad screen? Loose connections? Software glitch? Could I take it to the Apple Store to get the screen tested?

I would appreciate any help you guys could give me.

Best ways to take care of my iPhone 5?

I just recently got my iPhone 5 and I would really like to take care of it in the best way possible.
I don't want to take advantage and throw it around like most do. I want to ensure that I take care of it.
That being said, I've never had a smartphone before.

So I was wondering if someone could please advice me on the best ways I can take care of my iPhone. And that includes the case, the charger, the iPhone itself, etc.

What are some brands to use for a case.
And what are some ways to take care if my charging cable because I hear that it breaks a lot and my chargers always seem to breakdown before my phone.
(I heard that putting electrical tape at the end of the iPhone charger will prevent it from being bent and will stop it from breaking)

Any help will be great.
