i have MANY questions about my new iphone?

1) No it does not because you are putting it from your computer, not the internet. Just as long as you use the CABLE provided with your iphone 4s.

2) Yes of course it uses data, depending on how long the video it will use your 2gb data plan. You are watching it from youtube, that is on the internet.

3) No it will not cost because you are using your computer to copy the videos. Just as long as you use the CABLE provided with your iphone 4s.

4) When you download the app, it will use data (unless you are on wifi). All those apps will use data because they show ads from the internet but not much. Facebook and Instagram will use the most of course as Facebook is filled with pictures and so is Instagram. Starbucks, what kind of app is that? If it looks for the nearest starbucks of course it will use your 2 gigs of data because it needs the internet to find you the nearest one. Youtube uses LOTS of data because it's video and from the internet.

5) If it is a 2GB price it is a flat price just as long as you stay UNDER 2 GB, if you go over 2GB they charge you TONS, so ask before signing your contract.

No you don't pay less if you used 1GB out of the 2GB, you paid for 2GB. So if you are under, you lose it. If you go OVER, you pay tons over overage fees.
