8525 memory

[cbwhit]

Please forgive my ignorance but I need help. I have two 8525 phones. On both, we suddenly get a message that all memory is gone. Where is it going? Out of 41 meg, I can't account for why it goes from 16 or so available to no memory. The only solution I have gotten from Cingular is to clear the phone. That is a painful process. There must be a way to find out what is taking up memory. By the way, I have not added new programs and I put everything I can on the card rather than in the device. Help.
