Did my iPhone pick up radioactivity? - 1

Ok so I have an iPhone 4S, and yesterday I had my earbuds in without any music on, then suddenly my earbuds start making this really strange static noise, it sounded VERY similar to the static that comes from a device that is used to measure radioactivity.

How long should I leave my iPhone off and in rice after water damage?

My phone vibrated in to the bathtub tonight and I immediately grabbed it out, removed the case, sucked water out of the speakers/charger spot (yes that sounds weird but I panicked, this is my baby), dried it off and turned it off. I still needed to rinse off from my bath so I showered quickly and then put the phone in rice. How long should I leave the phone in the tub of rice before trying to turn it on?

Also, what else may help it dry out, I Really do not want to buy a new $600 iPhone, I'm a college student after all.

How to exit apps on iPhone 5?

I just upgraded from an android phone to the iPhone 5. On my android if i was running an app an just pressed home it wouldnt actually exit out of the app just take me home, & id have to click on this widget called live applications & exit the apps i was on. Is it the same with iphone 5? I don't want to use all my data because i'm not properly exiting out of the web, or apps like IG/Facebook & Twitter. If it is the same how do i properly exit out of the apps? Do i have to download an app/widget like the one i had on my android?
