Lost my iPhone, how do I find it?

I lost my iPhone and I have looked everywhere I can think of but I can't find it anywhere. I know that nobody stole it so I don't want to reset it and get rid of all my data and everything. And I do not have Find My iPhone installed. I know there must be some way to track my phone somehow. Could I call the apple store and could they help me? Besides getting a new phone? So please help me find some way to track my phone somehow. Thanks. (and I have tried calling it but it is on silent)

Will the dry rice method still work for an iphone if it has been switched on?

I dropped my phone in water and immediately took it out, dried it and turned it on to see if it worked. The phone worked but there was no sound so i googled what to do and i found the dry rice method but it said that you shouldn't turn on your phone but i did (maybe for ten mins?) so i turned it off and put it in a bag full of rice. Will the sound go back to normal because i turned on my phone?

Added (1). Should i put in the bag of rice with the back removed and battery exposed then?

How to TRACK MY ORDER ON AMAZON without being a member?

I made the purchase a month ago straight from my cellphone web browser without creating an account and selected a shipping method that was only supposed to take up to 22 days to deliver (can someone help me figure out which method this was as well)? I purchased an iPhone 4S charger cord and wall plug…

Are there any good Wi-Fi hacking apps?

Okay, I have NO idea what the hell the password is to my Wi-Fi. When I try to connect to a network, there's like three or four to choose from, all requiring passwords. We have a computer and I'm pretty sure we have a router (otherwise I wouldn't be on the internet via computer). I have limited data on my network plan, so I can't get on Facebook or Instagram or anything like that without eating up my three gigs. I hate using my computer because it runs so unbelievably slow. I have the iPhone 4. Thats it- just the 4. It isn't jailbroken and most of the Wi-Fi hacking apps require that your phone is jailbroken in order for the app to fulfill its purpose. Is there any good apps out there that will somehow hack and/or generate a password for me to get in? I'm 15, of course I'm gonna worry about this sort of ****. Anything will help.

Alltel iPhone 5 on straight talk?

I was wondering if I would be able to use my alltel iPhone 5 on straight talk? I believe alltel is CDMA, but there's a SIM card slot on the phone. I purchased the SIM card and when I put it in, it says that the SIM isn't valid. Would unlocking the phone solve this issue and how would I go about doing this?

Iphone camera remotely hacked?

My friend had someone text her saying that they could see them through the camera. This wouldn't be anything more than a troll except for the fact that they knew that she were at a friends house. They also tracked the phone to their location, which was the friends house. Please let me know if this is a troll or if it is legitimately possible to be remotely hacked. TY.
