You can rearrange your icons from your home screen into your applications or options folders (do this by highlighting NOT CLICKING and BB button move to folder....)
Do your normal battery pulls/ quick pull app!
Delete apps you do not use (you cannot delete some of the VZ apps unless you use a program to do it!)
in my opinion the quick pull app and the other one are simply too buggy. Just do the Battery pull it is the method used in the book also by all of our CB members. You need to check which apps are running. Do this by holding down the BB menu button. An icon bar will appear with a list of running apps. you should have only 4 working the phone browser messages and the home screeen. When you see that you have more apps just go to that app shut it down by hitting the bb menu key and selecting exit or close. Some programs like Viigo have had memory leak issues also talk lock the older version has leaks. If this dosnt work there is a thread here that has memory saving tips. I hope this was of some help to you.
