Unrooting questions
 

Hey so its about that time to upgrade my phone. im looking at the samsung G3 but anyways if i remember correctly sprint nor best buy will take rooted phones as trade in. So i unrooted my phone via: http://www.youtube.com/watch?v=ubojj...eature=related and it does seem to be unrooted or atleast when i try to use titanium back up it says something about this phone doesnt have root or whatever. but what concerns me is that if i go into about phone under software it says: Firmware 2.1-update1 and it wont allow me to update the phone any further. is that ok or does it need to say something different? thank you for your help
