internal storage - How can I deal with "Low on Space" messages on my Android?

I keep getting the "Low on Space: Application data space is low. To free up" [the rest is cut off] message.

I've moved every app I can over to the SD card, cleared the cache, compacted my K9 mail cache.

Advanced Task Killer (ouch!) says I have 98M Available Memory

File Manager says I have 223M/748M (29%) free.

That's not so bad -- but I'm stuck in the no-updates scenario. The market downloads won't really start, gmail won't update, etc. I've rebooted several times, and nothing changes. Aaaargh.

What can be done, other than uninstalling everything ?

What Should I Do When My Android Runs Out of App Space?

Here's the summary, in order of easy to hard:

1. 
   

   Move Bigger Apps to SD Storage - currently requires Froyo (2.2). Navigate to Settings > Applications > Manage Applications (or something similar). View the All Tab, sort by size. You can't do anything about the big hitters, namely Gmail, Browser and Maps will always be pretty big.

   
   


2. 
   

   Clear the Cache, and Maybe Data, on Some Apps Similar to #1, navigate to Settings > Applications.

   
   



3. 
   

   Clear Out Apps You Don't Actually Use Shouldn't this be #1? ;)
