I keep getting the messages "low on space" and now "storage almost full" in my notifications. Under "storage almost full" it says "Please make at least 512 KB free space to receive messages. Tap to manage your ap" I tap on it and at the top of this screen it has the column titles: Downloaded, All, On SD Card, and Running. At the bottom of the screen it says "Internal storage" and below that it shows 250MB used and 498MB free so I don't understand why it's saying my storage is almost full. In the "Running" column it shows processes that are running and at the bottom shows RAM of 158MB used and 209MB free. I have uninstalled a bunch of apps, keep killing tasks with Advanced Task Killer and I still get the storage almost full message and I can't do anything except make and receive calls. HELP!
