I bought my phone last thursday, and have been super carefull with it because my store had no cases, screen protectors, holsters...nothing. Planned to go to a larger store this weekend and buy something for it. Well yesterday on the way to the store the screen got scratched, I really dont even know what I did... I possibly put it in my pocket with my keys for maybe 30 minuted while in another store.
Anyway my point is these screens are very easy to scratch, I have seen the video that the guy keys his screen, while interesting and kinda funny it isn't really a real life scenario. I have even seen a post saying corporate reps say the screen needs no protection its very durable and scratch resistant, well I had the Iphone for 2 years in December and it had a screen protector on it less than a quarter of its life and its screen was 2x as scratch resistant matter of fact its still not scratched very bad.
Lastly dont buy the Verizon 3 pack I tried them yesterday and the fit isnt correct the guy at the store AFTER I bought them and was returning them said I needed to trim one side for it to fit correctly. I told him they are suppost to be already cut to fit and I wanted my money back. I ended up with the Zagg Universal Invisible Shield from Best Buy and put it on last night its not really hard to install and looks good, but it seems kinda sticky. I have heard it gets better after a couple of days of usage so we'll see.
Just thought I would let you know my experience and hope it helps some prevent scratches on there screens.
