Can't hear phone calls through my iPhone?

So. I had a little accident with my iPhone (dropped it).It was in its otter-box case and I thought it was fine but now, whenever I answer a phone call a muffled pop noise happens and I can't hear the other person or even hear the call being dialed itself unless its on speaker or I have the headset in. This is my replacement iPhone from the insurance - so how do I go about getting this fixed without paying $200+ dollars to Apple?

Side note: (Nothing's cracked, the speakers work - the mic works when it's on speaker I just can't hear the other person during a regular call unless I put it on speaker.)

How to get back into playing with toys?

I know this is an odd question but up until the iPhone came out, I was really artsy and LOVED toys. Now, I have an iPad and phone and can't seem to get off them. Any ideas?

Random apps appearing on IPhone 4?

Lost Iphone with Magic Jack installed?

I never changed my number and am using the same number on my new smartphone. Can the finder use my lost phone to make Magic jack calls? The lost phone had no SIM but i used it to connect to Wi-Fi for Magic Jack. Basically, does activating a number on one device cancel that same number's use on another. I googled and searched everywhere and couldnt find an answer. I haven't seen any abnormal activity with my magic jack number but will still change it. Before I change my number, I'm just wondering if anyone can tell me if there's no need to change it…
