How do I check which browser I'm using? Some context: I'm using Desire, and it bugs me that it adds "http://www." when I type a word into the address bar. I just want to search...

The application I'm using is called "Internet". Is it something tailored to HTC? Is it based on Chromium?
Go to Settings - Applications - Manage Applications - All - Select the icon you use and this will give you all the information about the program
