Sprint today announced a "maintenance update" for the Samsung Moment, complete with several system tweaks.

Here's what the update offers:

• Network Assist GPS to allow indoor location fix
• Updates to several third-party apps, including Visual Voicemail, NFL, NASCAR and Sprint TV
• Change to Emergency Dial on lock screen
• Hard reset available in recovery mode: remove and reinsert battery; press volume down, send and end keys until reboot option pops up; scroll to wipe data/factory reset; press OK
• Various improvements to battery life

The kicker?  The update is only available at Sprint retail locations with a Repair Center, so you'll have to venture out of the house to get it.  Given how busy the service and repair locations tend to get, I would highly recommend making an appointment before going in.  If you prefer not to brave the crowds, rest assured - Sprint says an OTA version will be available soon.

I've used the Moment, and I can attest that battery life is less than desirable.  Here's to hoping that the update solves the problem!  If you decide to get your device updated, let us know how it goes.
