Luckily for you...replacing the back glass is as easy as easy can get.
The front glass...not so easy.
If you are like me...and really enjoy the naked look of your phone...and don't want to cover up the beauty....then I recommend I nice bumper.
The bumper I always use, love, and recommend is the SPG NeoHybrid bumper.
It's perfect for a decent bit of protection...while still not completely covering up the beauty of the device.
It is 2 pieces.
One rubber piece, your first wrap around the metal antenna of the phone.
And one harder plastic piece that slips on over the rubber.
If you get the silver one, it almost feels like there isn't anything on it.lol.
If you had had an SPG NeoHybrid Bumper on...the back glass would not have broken.
The bottom rubber piece slightly protrudes from the edge of the glass on both sides, preventing the back/front glass from touching flat surfaces.
I actually had my phone *ran over* by. Pickup truck while it had the SPG bumper on it...and yes...I think it did save my phone. The screen protectors got a little scratched...but underneath the screen protectors was a sparkling scratch free screen.
Tho if you are working hard labor work or out and about doing something where you risk dropping your device...then i recommend you get an Otterbox or something similar for those particular situations.
I have the Otterbox defender case..and while it is pretty bulky, it adds ultimate protection when I am out skating.
When I I get home, and am done skating for the day...I take off the Otterbox and put in the SPG.
