First of all delayed thanks to CJM, BlacknBlack and Justis.
I now know how to make ringtones and use them.
I am getting familiar with "TB'. I have dowmloaded lot of free apps which have resulted in decreased battery life. I have a few "App Killers" but no matter how many I 'kill", same and other apps again pop up in a matter of seconds. Is there some way to control this? I know I made a mistake in allowing several apps to have "notifications". Even in "setting" disabling notifications etc does not help.
