What's causing my iPhone touchscreen problem an?

When I hold my finger on the screen, it shakes. WHen I type, a ton of other keys come up, so if I press One letter a random string of letters follow, occasionally I'll encounter a random click outside the keyboard when I type. At least autocorrect helps lol…

I'm typing this from my phone while riding in a car on a bumpy rd. Is the screen on a iPhone 4S linked to the gyroscope? If it is, how do I turn it off? I only have this problem on bumpy. Roads; the touchscreenk works fine anywhere else

I'd like to change/cancel my Vodafone contract, am I allowed?

The contract I have seems to be overpriced and half of the plan goes unused, would I be able to cancel early or change contract to either another plan or another network?
As the contracts for the iPhone 5 are cheaper than the options I have on a 4s by a decent margin.
