I might have went a little over board but this is what i got for my phone
1. Invisble Shield full body cover, it's a clear plastic and is aplied to the front screen and the back and sides of the phone (1 major piece for the front, 1 major piece for the back and 4 smaller pieces for the chrome on the sides) There are youtube videos of people trying to put it on, it looks time consuming. I went to my local mall and they have Invisible Shield kiosks where they apply them for you for $40 (product and installation)
2. I also bought a Incase protective cover, it's a type of rubber case. I wasn't comfortable with just leaving the phone with just the IS protector, if i droped it the phone would break, so this gives it cusion and me, piece of mind.
