I'm copying this from another post because I don't want it to get buried. This is for everyone out there having trouble getting Live Wallpapers to work on their Moment.
I give FULL credit to the other posters.

*6/30 EDIT! - The new links are now working properly! Go crazy!
-This post is assuming you already have the 2.1 update-
Files Used:
CCLeaner
OLD CL14 SAMSUNG INSTALLER
New Recovery File
Live Wallpaper ZIP
-Follow EXACTLY. Don't deviate-
1) Go to Control Panel. Remove EVERYTHING Samsung from your Add/Remove section. This will remove all of the drivers etc.
2) Go to your Program Files (x86 if needed) section under 'My Computer'. Delete the 'Samsung Electronics' folder.
3) If you have
CCLeaner and are comfortable using the Registry tool, clean your registry of anything Samsung. This will ensure that your new install doesn't use the old stuff.
4) RESTART
5) Install the
OLD CL14 SAMSUNG INSTALLER onto your PC. This is important as the NEW installer won't use non-signed packages.
6) RESTART
7) Download the new
Recovery and KEEP IT IN ITS DOWNLOADED FORMAT. Take off the MD5 at the end of the file so it ends in TAR.
8) Go back to the Samsung Electronics folder (that you would've deleted earlier) and head to SWUpgrade\Models\Binary. Remove the file inside, probably called "SPH-M900_MR2_DE03_REL_1.tar". Delete it, move it - whatever.
9) Copy the Recovery file you just downloaded into that folder. DO NOT EXTRACT IT.
10) TURN OFF YOUR PHONE and remove the battery for about 10 seconds. Replace battery. DO NOT TURN IT BACK ON.
11) HOLD '
VolDown+Camera+End'. A DOWNLOADING screen should appear.
12) Start the SWUpdate that should be on your desktop. Otherwise, it's back in the Samsung Electronics folder from earlier.
13) FOLLOW THE ONSCREEN INSTRUCTIONS EXACTLY. I can't stress that enough...
14) After it applies the Recovery file (which is why you placed it in the Binary folder), RESTART YOUR PHONE.
15) Copy the
Live Wallpaper ZIP file to your SDCard. DO NOT put it into a folder. Just copy it to the root of the card (meaning it's by itself and not in a folder). DO NOT EXTRACT.
16) POWER OFF YOUR PHONE
17) HOLD '
VolDown+Call(Green)+End(Red)'. This will put you into Recovery Mode. Using the VolUp/VolDown keys, scroll to 'Apply Update.zip' and press the center key. Select the Zip File you just copied to your SDCard. After it processes, RESTART YOUR PHONE.
18) BOOYA! After your phone boots up, you should be able to hit Menu then Wallpapers and you should see Live Wallpapers as a heading.
This doesn't ROOT your phone, only adds Live Wallpapers to your Moment.
If you want to run CUSTOM Live's, you'll need to ROOT your phone. After the zip is applied, you can delete it from your SDCard.
I hope this helps. :-)
