When a new update is available, is the size of the update (mb's) added to the original size of the app, or is the app entirely overwritten with the update? I saw a thread on here awhile back in which someone was complaining about app updates and trying to make a case for never updating. One of their arguments was the memory used by all of the updates. I haven't really tracked it, but I would think that by accepting all of my updates, if the file size was "added" to the original app I would have run out of space by now or at least made a major dent in my designated app memory (Droid Bionic). That doesn't seem to be the case, but I was still curious. Example: Original App "ABC" is 5 mb Update to "ABC" is 5mb. Is App "ABC" now using 10 megs or still the original 5, just overwritten with the new update?
