I'm trying to get rid of Other on iPhone 5?

I know this is a tired question because no one can figure out how to truly remove the (5GB in my case) excess of "other" on the iPhone because it apparently might be due to corrupted files. I've tried everything I can find online to no avail. I really don't want to resolve to starting a new phone because I need my current photos, contacts and messages. Any suggestions?

My iphone got wet, won't turn on

On friday my waterbottle leaked onto my phone in my bag. 2 hours later, i noticed something very hot in my bag and it was my fone! I immediately tried to turn it on but it did nothing except the flash was on. About a half an hour later, i placed it in rice where it has been all weekend. I occasionally took it out and tried to turn it on this weekend but all that happned was the flash turned on. I have it charging now but it still won't turn on! Please tell me how to fix this!

I'm skinny and want to get abs?

I'm male, 15 years old. I'm skinny (5 feet 7 inches, 120 lbs). I do track and field every day after school (3 days running, 2 days stretching). I do a 5 minute workout every other day (iPhone App: Daily Ab Workout FREE), I also do 150 push ups (using a chair).Am I doing everything right? Also, do I have to run more after track and field in order to get abs? I'm already skinny.

My iPhone 5 got stolen! Is it possible that I might get it back?

As it says on the top, I got my iPhone stolen on Thursday on the train coming home from school. Yeah some idiot snatched it out of my hand while I was going to call my mom. The police made a report and stuff. They said its been going on since Monday. They said that we shouldnt disconnect the phone's service because that way, the police can track it down if the dude who stole it, sells it ilegally.

I'm kinda relieved that its a possiblity they can track it but here are the two big questions.

1. If the dude who stole my phone sells it to an ilegal phone service, can the phone service activate my phone for a customer even if it still has my phone number and service? Is it possible?

2. Since I never knew of the Find My iPhone app, can I still intall it on my computer to my iphone? (I'm an Apple Newbie I don't know)

And again, Is there any way I can get my iPhone 5 back please?
