Know your Android phone
It usually becomes problem to find & run application from your android phone, when you have lot of installed applications.
A useful app from google called ‘Gesture Search‘ is very handy in this case.
Install this app from market and place the widget on home screen. Launch the app and select settings, uncheck contact s.
Now draw first letter of the application you want to search for. It will list all applications starting with that letter. In the screen shot attached I have searched for facebook.
I find this app really very handy.
Please note to uncheck contacts and music from your search results. Otherwise it will list many results.
