I CAN'T FIND MY IPHONE

As always my phone has the find my iPhone app running at all times but my phone can't provide it's own hotspot (Wi-Fi). I logged on to the app on a different device and it can't locate it. I tried the play sound but I'm not sure it's working cuz my iPhone always has earbuds attached. Please help! I'm not sure if I dropped it while getting into the car, it fell in the cracks, or I just misplaced it in my home. (I'm not sure about that last one cuz my phone gets Wi-Fi here).Is there any way to find it! And please don't tell me to backtrack it cuz I already did that.

I'M FREAKIN OUT!

Added (1). Btw, I don't hav any phone service cuz I didn't hav the money so the calling option is out. I hav lost so many things (I hav a list) so this isn't the first time I lost it. Also, if I bring it up in my family, it would cause a ruckus, brothers looking everywhere, dad trying to find it by asking questions, and mom with a "I told you so that she wasn't responsible enough" look at dad.

Is there any way an iPhone can be unlocked without knowing the passcode?

My principal took my phone and demanded that I write down the passcode for it. I refused. So he said "Well, I'll keep your phone, and I'll call your mother and me and her can go through it together."

I don't think he has a right to go through my phone anyway. But, does he mean that he is planning on cracking the code or something? Can he do that? Is it possible?

btw, the passcode is pretty complicated, letters and numbers, i don't think it could be guessed.

If i delete my apps off my iphone and then get the update can i get them back?

If I update my iPhone 4 with the new iOS 6.1.2 update and delete some of my apps, will I be capable of restoring those apps after the update? I don't have enough room for the update right now unless I delete some things off my phone, so if I deleted some of my larger apps, would it work and i be able to get them back?

White iPhone 4s has better screen than black 4s?

My mom has a black 4s and i have a white one. They were bought from the exact same store on the exact same day. The black one has more of a washed out screen and not a true black its like a washed out black. The white one is much better… When starting up it is pure black unlike the black one. I had this exact same case with a black and white ipod touch. Why is this?

Ebay Buyer paid for item but won't go pick it up?

A buyer on ebay bidded on my iPhone 4S for $460, and the next the I shipped the phone after I got paypal confirmation that he paid. I also shipped with signature confirmation but the problem here is after the 1st attempted delivery by USPS, the phone will sit in the post office for 15 days before being mailed back to me. This is my only phone, I was hoping to use the money for this phone to get another. AT the moment, I'm phoneless. I sent the buyer two emails, one stating the tracking number and the second to tell him that the phone is at USPS, waiting for him to go get it. He has yet to reply. I called him today, some lady picked up and said he was going to go get it today.
it's 3:15. The post office is closed and he never went.

I paid ebay and paypal fees plus shipping. What do I do? :/
Those fees are coming out of my pocket.

Added (1). Paypal withholds the payment for 21 days…
the buyer can file a item not received and get every penny back

How to fix an iPhone that has been wet?

I had my phone in my purse yesterday and my water bottle leaked, wetting my phone. It only wet the top part; my camera had water in it and my flash would not turn off. The screen was flashing different colors. My friend fixed it and it worked for about an hour, but when I came home it slowly shut off. I've had it in rice for about 20 hours and I'm plugging it up now, but nothing has happened for about 45 minutes. What can I do to fix it?
