Private Browser is a Fast, Full Free Screen Browser for Android. It works with Android 1.5 and up. Private Browser also allows you to change the browser id (User Agent String) to mimic other browser (ie, firefox, safari, iphone,ipad), so you can view full versions of the sites or enhanced mobile sites.
If you press the search button, it will clear all caches/history and take you back to Google.
Due to a bug in Sense, Private Browser doesn’t work on Sense UI phones before 2.2. Its currently unknown when private browser will work on Sense.
