First thing to do is see what applications are running the in background. Hold down the BlackBerry button and a small rectangle box will appear showing the applications that are currently in use. Some of the apps are always running: Phone, BB Messenger (if installed), Home, Browser, and Messages. If other apps you are not using are still running, close them. See if that helps open up some memory.

Many believe just exiting an app closes it. However, if you don't close/exit from apps such as viigo or ScoreMobile your memory is going to be eaten up by them.

Also open Browser and then click options, then you will see Cache Operations, click it  and push every button in there to clear memory, one will ask for you to select delete or cancel, be sure and click delete. Then when you go to back your way out it, ( uturn button, next to red phone button) will say cleaning memory.  You can also click on options and see how much memory you have now by scrolling down to Memory and clicking it and a small scroll will show how much is there. Then in options you can scroll down to Security Options , Advanced Security, and then Memory Cleaning. Then scroll down to Certificate search ,click it and then click it and then select clean now. Then have you ever cleared phone log?  Push green phone button at bottom of phone then middle at the top of phone and look to the bottom right and there should be a big red X, keep clicking it until all calls are deleted.

 Oh last thing is pull bat. and wait a few minutes and re install and then push red phone button and set aside until it all starts back up. Then push options and see how much memory you have. I got rid of Slacker radio and am only using Pandora radio, as I read Slacker was a cause of memory leaks.

Please report back, and if this helped please give me a Kudo.
