Sorry to jump in here, but I was reading over this thread and I have a related question: how do I delete an apps actual DATA and not the cache? I just installed the Quick App Cache Cleaner app and my apps all have low cache.
Let me give an example: I use K-9 Mail for my mail, and it says I have 73 mb of data. I know that's old messages because there are 3878 messages in the trash folder. How do I delete those messages? Is there an app for that, or am I hunting in the K-9 settings?
Thanks,
Harry
