Today, Sprint is rolling out a service software update for the Samsung Moment, which unfortunately is not the update we heard from back on December. Back then the carrier promised that this Android handset would be getting a firmware update to Android 2.1 on the first half of 2010.
The latest software update to the Samsung Moment is to version S:M900.8.0S.CL14, which includes Network Assist GPS to allow indoor location fix, updates to several third-party apps, including Visual Voicemail, NFL, NASCAR and Sprint TV. There's also a change to Emergency Dial on lock screen and other various improvements to battery life, as well as a 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.
To find out which software version is running on your Samsung Moment go to the main screen and press Menu, tap on settings, then tap About Phone and you'll see the software version listed under the Baseband version heading and will be in the format of S:M900.X.XX.XXXX. If you own a Moment and need this update, you need to visit a Sprint retail location with a Repair Center, since the ability to download it directly on your Moment is not available at this time.
