I think my iPhone is broken?

Well a while ago i went to check my phone and i noticed it wouldnt turn on, i thought it was weird because i checked a couple minutes before and it said i had 71% battery left but i thought no big deal so i put it back in my pocket. But when i went home i checked again and it still wouldnt turn on so i charged it. Its had about two hours of charging and it still didn't turn on so i plugged it into my computer but its acting like nothings plugged in. Now i'm really worried any ideas on what to do? Should i go to the Apple store and ask them? Is there some sort of special way to turn it back on?

Can I be sued by an eBay buyer in a different country?

In October I sold an iPhone on eBay. Buyer paid, I mailed the item. After a month or so she contacts me and says that it's held up in customs and they won't give it to her. I told her there isn't anything that I can do about that. She asked if I could have the phone sent back to me, and then send it to someone in the states who will bring it to her. I agreed, and contacted the post office to have the phone sent back to me. I never received the phone and now 5 MONTHS LATER the buyer is demanding a refund and threatening to sue me and call the USA police. She is in Germany, I'm in the United States. Can she really sue me over something that I have no control over?

IPhone 4S: Any way to turn off Read text feature?

Depending on who I'm texting (and, I assume, the type of phone he or she uses), I'm notified as to whether or not that person has read my text. The word "Delivered", which appears under my text after it successfully goes through, changes to "Read" upon the recipient opening our text conversation. I imagine the textee in this instance is also able to see if I have read their text or not. Is there any way to disable this feature so that neither party knows if the other person has or hasn't "read" their text? This is not a matter of grave concern; I just find this facet of the iPhone slightly creepy.

My Dell Studio 15 laptop isn't finding any Wi-Fi networks whatsoever?

I've had a problem recently that my Dell Studio 15 laptop (it's only a couple years old) hasn't been discovering any Wi-Fi networks whatsoever. Like none of them show up. AT ALL. I've tried resetting the network adapter, turning it off and on again, resetting the router, modem, etc. I don't know what else to do or what I'm doing wrong. The only way I can get my laptop to connect is through an ethernet plug. I know it's not the internet connection itself because my iPhone and iPad have no problem connecting. I know it's not too far away - I live in a house on the smaller side, and it won't even discover my home network when I'm right next to the router. I can't even begin to imagine what I'm doing wrong, and boy, do I need help! Any and all advice is appreciated; thank you very much!
