I'm no expert, but you can check into this and see if it helps:

Hit the taskbar (top right icon) and tap on the icon of a chip (rightmost) to pull up you memory page. Under Storage/Free you probably have a number less than 1 MB. Whenever this happens on mine everything gets unstable and slow. To fix it I go into SMS messages/tools and execute either Empty Deleted Items or Clear "Text Messages" or do both. You also free space by going into your email accounts and clearing them out. ie. Delete most or all of your messages, then Tools/Empty Deleted Items. Then if you look at your FREE memory you should have made several meg available. I think you can clear your call history as well but these two things always do the trick for me.

HTH!
