Your problem is cumulative memory bleed. You get junk files left over after app deletion and eventually all Java powered BB's need their OS to be re-installed or updated. It will make a huge difference.
Also, a battery pull every day or two will help considerably too. Posted via BlackBerryForums.com Mobile
