Where did my iPhone's backup files go?

Can't find them anywhere on the computer. If that's not the way, how do I transfer the files of my iPhone to my PC ( without using bluetooth, I use iPhone 4, so bluetooth won't work) ?

What's the most complicated human technology so far?

This is for you thinkers out there. Say you could live forever. And you had the exact plans on how to make a technological object. What object would take the longest to build? Remember, you would have to start from complete scratch. That means finding a rock, to mine other rocks, to make metal tools, to make more metal, to then form into everything else. I think an iPhone would be one of the hardest/ longest things to build. What do you think?

Will everything get deleted if I change my SIM card on my iPhone 5?

I just a got a new iPhone but they gave me a temporary SIM until my new one comes. If I put in all my contacts, photos, download apps, and sync music, will it all disappear when I get my new SIM card or is everything saved to the phone? I really don't want to have to do everything again haha

I sold an iPhone 4S on eBay, shipped it with signature?

The buyer contacted me through a message on eBay and asked when I would be shipping the phone, and I wrote her back. When I went to print the shipping label through PayPal, it said it was not a proper address because it was a PO Box. It had to have signature confirmation, and I wrote and told her that. She wrote me back and gave me another address. I printed the label and had it picked up by my post office and sent priority mail. I kept checking tracking, and it showed out for delivery on July 3rd. Then that is all. It never showed the status as delivered. I called the post office there, and they had no confirmation and no package and were rude to me. I just figured she got it, or I would hear from her.
Then just today, I got a message from PayPal that the buyer had filed a dispute, claiming she had not authorized the transaction. She never contacted me at all. Then I contacted her and told her if she did not authorize it and wanted a refund, I'd be glad to, if she sent the phone back. She wrote back and said that she does not even have an iPhone and didn't authorize it. The message said "Sent from my iPhone". I contacted PayPal, and they said I'm covered by the seller protection, but they have to investigate. They said if I can get a tracking showing it was delivered, they would release the funds to me.

iVisor: too expensive
I-Blason: doesn't make it for the 4
GreatShield EZseal: doesn't sell it/I can't find it anymore
