OK - This may sound stupid, but I;ve been unclear about this for a while, and the ability to delete files etc, as root has confused me further: 1. Re: "Internal Memory", as defined in the SD Card and Storage (maybe not right words, phone not in front of me) Pref Panel - Clearly that is where your downloaded apps are installed and stored, right? Is that also the "space" in which the apps are run? That is what I had thought initially, but looking at the "Free space" in System Panel app does not correlate with the "Free Internal Memory" number in that pref panel. The free space in System Panel app goes up and down as I open and close apps, as I would expect. 2. What do you all have as free internal memory? If I start with 160MB, how do I only have 20 remaining?? I do NOT have 140 MB of apps installed! I have relatively few, maybe 20 apps, I don't have games or many themes or wallpapers or any of that. So what else is using this space? What do you people with lots of apps have as free space? 3. Deleting stock apps (Peep, Twitter, Stocks, etc) deletes them out of the system/apps, which is NOT the same space as user-installed, right? So I don't gain anything by deleting them? 4. I know apps2sd makes some of these questions moot, but I want to understand. Thanks in advance for reading and contributing your knowledge.
