Apple ipod

What is the best for the iphone to a student?

I can get an iPhone soon, and am undecided on this case to obtain. My phone Will be launched in my backpack and lower times, but I do not like giant waterproof / scratch-proof rubber holster. Otherwise what would be ideal for me?

The best case for the I-phone is the Otterbox http://www.otterbox.com/
