I'll occasionally go into the "manage applications" section to check on the amount of memory some of my apps are using. A few days ago the "dialer storage" app was using less than 1mb of memory. Now it's up to 5.13mb. I have noticed it fluctuating before but I have no idea what causes it to do so. It's really not that big of a deal but I'm just curious if anyone has a clue. Thanks.
