Why do the "Successfully updated" notifications disappear?
This is a new 'feature' in market version 3.x, which got pushed out some time last year to gingerbread devices. If you have a rooted phone and really want the old behaviour back, uninstall the 'market updater' and install android market 2.3.6 Here's an apk of it from my dropbox https://dl.dropbox.com/u/2302883/com.android.vending-5cbc09eeba96ab104fe111e029312f42.apk.gz
