How to control my pc from my iPhone?

Iphone fell and won't turn on

Okay, so this is my second screen for my iphone, the first one i dummied.i've just recently dropped it again and it has at least two cracks around it. Today at work i dropped it on its back (so that the screen was facing me) it has a case so i wasn't too concerned, when i went to text someone however it wouldn't turn on? It was just a black screen. I tried turning it off i tried rebutting it (press the back button and top button at the same time) and it wouldn't do anything, finally i went home and charged it. That little sound it makes whenever you plug in your iphone came on BUT NOTHING HAPPENED. Its now been making that noise ever 7 seconds but the screen won't turn on and i've tried rebutting it twice. And unplugging the charger. However last night i went to grab my phone from my room and the background was one of those automatic background instead of the one i put on myself… All my pictures, msgs, games were saved but auto correct and spell check were turned back on? I didn't think much of that either because i had everything saved. HAS THIS HAPPENED TO ANYONE? Does ANYONE have any idea what's going on… I not only am alone this weekend and need my phone desperately, i also have no way of getting to any kind of apple shop… Is there some trick i can do? Please! Someone help!

My iPhone 4S won't charge, but will connect to itunes?

Since yesterday my phone will connect to my computer and wall outlets but will not charge. It keeps making the 'connect' noise, and that's it. The phone does show up on my computer like I said, and I can manage, sync and restore. I tried a restoration on the phone and it's still doing the same thing. If anyone could please help I'd greatly appreciate it.

IPhone 4 volume button doesn't work, water contact?

I'm asking this question for my cousin.

So, he just bought an iPhone 4 off ebay with warranty. However, the phone's volume button doesn't work. After he brought the phone to Apple to repair, they claimed the phone had contact with water and their warranty won't cover it.

My question is: could water damage affect the volume button in such a way it render it useless?

Thanks!

Added (1). Well, I can say it is very hard to sell a phone with defect at a suitable price. Even if he were to sell the phone back at the price he bought at, he still has to pay a cut to eBay and paypal. If he leaves a negative feedback for the seller, the selller is going to do the same to the buyer -- eBay really sucks in this area…
