Which phone should I purchase?

I think I have finally decided to get a smartphone but I can't decide between the two. The two phones are the HTC Inspire 4g and the iPhone 4g. I'm a teenager so I love apps and I know both of them have apps but I'm also a super social net worker and i'm always on the internet. I talk and text all the time and i'm really ruff with phones. I know both phones are really great and I like them both, but I just can't decide.
