This is a a list of Android applications that I currently have on my phone. Some are more often used than others, but all are useful.
These apps are running on my Sony Ericsson Xperia Arc, which has Android 2.3.3 on it. Most of them ran on the Sony Ericcson Xperia X10 as well.
ADW Launcher is a fast and feature rich home application replacement. Use it instead of Sony Ericsson's TimeScape and your phone will feel faster.
