What is the cheapest iPhone 5 plan available right now?

I want to buy an iPhone 5 this summer. I'm working the entire summer--minus a few weeks where I'll be at camp, vacation, etc. Buying the actual phone is no problem, but it's the monthly bills that I need to do research on. My mom is EXTREMELY cheap, and I want to have a good solid cell phone plan when I ask her if she'll pay the monthly bills. What's the cheapest plan available right now? What carrier it is doesn't matter, but Verizon is preferable. If there's something cheaper, though, it doesn't matter what carrier.
Also, are there cheaper plans for the iPhone 4s? I'm willing to buy the 4s if it's even cheaper than the 5 plans.

Can I connect my PC to our home Wi-Fi using my iPhone or ipad?

I want to connect my XP desktop computer to the Internet, we have a Wi-Fi broadband at home and I use my iPhone and ipad to connect to the Internet. Anyway, the pc itself has not Wi-Fi connector, so it must be wired.

I was thinking, how can I get my computer to access our home Wi-Fi by using my iPhone as the connector via USB? I do not want to use the phones 3G or mobile connection however, so tethering to 3G is not an option. I want to specifically use my home broadbands Wi-Fi.

When will iphone with larger screen come out?

I went to checkout iphone 5 but the screen size appeared to small and i wasn't impressed by that. Android phones can reach 5.5 inches in size. I ended up buying LG nexus because its screen size and visual display is better than iphone, yet cost if about half.

Benefits of large cell screen --

1) websites viewed with more clarity

2) Videos and online streaming looks more real and impressive

3) Work gets done faster. With large screen, less time is spent scrolling the browser and texting is faster too.

4) Eye strain is less. Larger objects cause less stress to the eye.

Ideally screen size should be at least 4.7 inches to make it suitable. 5 inches is a plus and anything above that is incredibly good.

But screen size must not reach 7 inches, because it will not fit pocket.
