When your Samsung Fascinate inevitably informs you that it's ready to download an "i500.DI01" and you scour the web for news, you'll likely be disappointed to hear that no, it doesn't include Android 2.2. The update will, however, improve your notification system, more easily sync your email, switch faster to 3G data from 1.x (possibly the same issue that plagues the Droid 2) and improve the ability to search your phone for that all-important grocery list without hanging up on your beloved. In other words, unless Verizon omitted the inclusion of a nasty bug in the release notes above, you've got nothing to lose. Except that "No Service audio alert," of course. Can't imagine why Verizon would go to the trouble.
