Updated an hour go with odin and im really pleased. GPS, compass work great, getting better signal, doesnt have the lag that the last official update had.
I dont see what all the commotion is about.
People using kies should just Odin, yea it wipes but probably better that way so you dont run into intermingling, compatibility issues
if you dont use a pit file it will not wipe.... soo if you dont wanna lose anything give it a whirl. I used to always do the full wipe before but i got lazy this time
