It sounds like people have troubles with gps and 4g after going to 4.4. Is there anyway to maintain their functionality?
As said above, use Titanium Backup, and your data will be recoverable as long as you have your nandroid backup (the one you made in the backup step of this guide), otherwise yes, you will not be able to access app data. Though anything on your internal/external SD will remain, such as Pictures, Music, etc.
GPS works, but Google removed regular 4G (Non LTE) support with 4.4, not much we can do. D:
