I was actually looking at that, question though, will downloading that mess up my media (pics, ringtones, music) or my contact list?
Not sure since I am on VZW, but even if you don't try the things in that thread, you should be backing up your device regularly. Backup your contacts, pics, ringtones, etc and you can restore them when you get your phone working the way you like.
