adb remount adb pull /system/app/LiveWallpapers.apk LiveWallpapers.apk
Then proceed as directed in the first post.
Anyways, I don't have the ability to pull the original Live Wallpapers... would it be possible for someone else to pull theirs, and post the APK online for me? I've been using "AppInstaller" to implement all of the APK's I've downloaded. Just been playing around with the Galaxy S LWPs. If it's a hassle, don't worry about it. I'll figure root soon enough.
Thanks for the quick reply, by the way!!
