I have heard complaints of people who backed up their apps with a file manager (Astro for example) and when they wipe the phone and reinstall the apps from the backup, it does not bring back the "Downloads" list in the Marketplace. No problem, except that the Marketplace uses this list to remind you of updates to applications. Can any one verify either side of this question from personal experience. Wiped and able to restore from the marketplace? Even if google remembered, how would it tell you? Would the Download list have a bunch of entries that say "previously downloaded"? Does it look on your phone and detect which apps you have installed and compare it to the list of downloaded apps to find discrepancies? This seems unlikely.
