Speakers on iphone don't work?

Alright, so a few weeks ago I had the glass on my iphone 4 replaced. I don't have insurance on it, so that was the cheapest way to get it fixed. Well since then, the speakers on the phone don't work. I have tried reinstalling the software but that didn't fix anything. Now there may be a wiring issue that occurred when the glass was replaced but the company would need the phone over night to fix it and I don't have time for that. So if anyone has some advice that would be great!

What works/what doesn't:
-Phone calls work, the person can here me/i can hear them.
- speaker phone does NOT work. I hear nothing, other person can still here me.
- Phone doesn't ring or play music.
- One app (Zippo app) works just fine, I can hear all the sound effects normally when I turn it on.
- If I'm in a call and go to text someone, the sound works… I hear the key clicks and it beeps when I get a new message (again, ONLY if I'm currently on the phone with someone)
Everything works normally if I put headphones in…

What is a good app to download free music on iPhone 4s?

Why can't I sync my iPhone 4?

Here's the situation:

I had a MacBook to which my iPhone 4 was synced. However, for reasons unknown (dun dun dun) it crashed, and so I acquired another one. Now I'm unable to sync my iPhone 4 to this computer (OS X 10.6.8). Not only that, but the iPhone will not even appear in Finder, iTunes, or iPhoto.

Now you might be thinking, "Hm, maybe the cord or the port doesn't work." I thought of that too. Upon further investigation with "USB Prober.app" I found that my computer can tell that there's an iPhone connected to that USB port. So the cord itself is not the problem.

So far I have: restarted the computer, restarted the phone, updated the phone to the latest iOS, checked to make sure both the phone and the computer are authorized, and done an insane amount of searching on the internet machine. Still nothing. All I have left to try is to download a fresh copy of iTunes from Apple, unfortunately my internet runs at about 40kbps so it'll be some time before I can try it.

I await the infinite wisdom that is the internet to enlighten me…
Else rage-quit.
