While not nearly as big a deal as the Froyo rollout for the Droid X, Verizon is also releasing an update for the Samsung Fascinate today. Doesn't look like users will receive a notification for the update quite yet, so to get it you'll need to check for it manually.
Instant notification of Visual Voice Mail messages on your messaging bar.
Improved syncing between your phone and email accounts.
Prompt notification when switching to Airplane mode.
Faster switching to 3G services from 1x.
Easily search your phone during calls.
Improved Enterprise Exchange password alerts.
No Service audio alert removed.
Like we said, a fairly minor update, but obviously any improvements are welcome.
