I'll tell you what i had the S3 for two days and i returned it because of guilt! I went back to the store and bought the iPhone 5 after speaking to a forum member and my brother. They both steered me toward my purchase today and I cannot be happier! This thing is FAST! I mean like really freaking FAST! The motion of the screens changing over, or apps opening is so fluid it's incredible. I get great reception/service and I just really enjoy it. So glad I went in this direction!
