I have the Internal memory Widget on my homescreen and in the past few hours the amount of internal memory used has jumped from 92mb/147mb to 118mb/147mb. I'm struggling to figure out why. I have Mobile Internet enabled as always, and I use several well know apps and widgets like Sky News, BBC News, Chomp SMS, Twitter, Facebook for Android, etc. I've checked every app using Settings > Applications > Manage Applications and only a couple of apps had a cache size over 1mb, most didn't have stored data at all. Facebook had about 4.5mb of cache data, but all this adds up to a total much less than the 26mb increase that the memory widget is reporting. Anyone know what could be filling the storage?
