My choices are the iPhone 4 and the HTC Aria.

I was really looking into the Aria since it is a Widows phone, it is an android, and many other reasons. But I also like the iPhones. So please list the pros and cons of both. I'll need the one with the best battery life because I am a textaholic since I am only 14.
I really like the iPhone, don't get me wrong it is a good phone. But I like the Aria too.


Please don't say the HTC or iPhone just because you have it. Thanks!
