Should I get The S3 Or The 4S?

I'm asking because I most of my time on Youtube twitter Facebook and tend to watch movies. Also If I buy the 4s I won't be able to listen to music without my parents knowing also my parents won't buy me apps on the 4s. Mean while on the S3 I can do this because my parents have all apple products except for me and my sister also I do a lot of lenghty school trips but the only problem is that I'm used to the iphones interface and sort of rusty with the S3.So Should I Get The S3 Or 4s

With the information that you've provided, I think you're better off with the S3. You explained that you spend a lot of time on Social Media websites and watching videos.

The S3 has a larger screen than the iPhone 4S's 3.5" (diagonal) display making media playback and internet browsing more enjoyable. You'll adapt to the interface over time. Neither phone's battery life is great.

You also need to take into account what computer OS you currently use, obviously if you own a Mac, the iPhone 4S would work more flexibly into your everyday life.
