Just an FYI, the glass on the iPhone 4/4s is very different from that of the 3Gs and prior. While the 3gs and older models had a very tough, almost I breakable glass, the new models are actually quite delicate. I used to drop my 3G over and over in my home and on concrete and it did not get a single scratch on the glass. My wife's iPhone 4 was dropped from about 1.5 feet off the ground and the glass shattered. I mean literally shattered.

I was surprised as my 3G was able to take quite a beating. After researching online, I found the glass was different. So, I picked up a leather SENA case which flips open when I use the phone and stays shut when I don't. This keeps the screen covered in case of accidental drops. Very pleased thus far.

I would get something over that screen as its an expensive fix (we didn't bother fixing the wife's. Purchased two new 4s' instead).

Cheers

Since you already bought screen protector, and want to buy new one or other to help them install phone protectors. I watched a vid on how to do this, which I apply on my phone and great it works. I hope I will also you and others.

Here's the vid:
