I got a message today saying "Internal phone storage is low". Not the USB storage, and not my SD card storage, but the system storage. It said out of 2GB I had 167mb free. I went through the few apps I have installed and deleted those that I hardly used. That now gave me 369mb free. I don't get it. I added up all of the apps I have on the list and it only equals 325mb, Facebook being the highest at 59mb. So if I'm using 325mb out of 2GB how is that full? I've emptied the cache and temp files. Can't seem to figure it out.
