Why does my iPhone screen click when I press on it?

It's my front screen that does this, I have an iPhone 4S and I got it a little less than a year ago, I've dropped it quite frequently but it has no cracks, I have a front screen protector and used an otterbox for a long time and lately I've been going without a case and have dropped it about 3 times and luckily none of these resulted in anything more than scratches and little chips to the borders of the glass. Anyways, when I press on the front screen, with more pressure than a tap, it clicks, like I'm popping it into place or something but it continues to do this. Everything else on my phone is working fine though. Should I be worried? Is there something wrong with it?

I lost access my iTunes library?

A few months ago, I bought a new iPhone and I synced it up to my iTunes library. I have about 300 songs, 30 apps, and 700 pictures. Since then, I bought a new laptop. I attempted to sync my phone to the new laptop, but it says only 1 computer can have my library at once. My old laptop that had my entire laptop has since been sold, and I have no access to it. Is there any way I can remove my library from the old laptop without access to it? I really want to sync my phone to iTunes in case I need to back it up, but it won't let me. Please help me. If I wasn't specific enough feel free to ask any questions. This is really important to me and I don't want to lose all of this data.
