IPhone water blooper - advice please?

I dropped my iPhone 5 in a creek - yes, a creek; I know how it sounds. Luckily the water was only a foot deep, but it took me a good deal of time (probably 15 mins or so) to find the phone because the creek wasn't exactly crystal clear. I wiped it off, brought it back to my house and quickly put it in a sealed bag of rice, but I didn't turn it off right away because I was afraid it would short out. The next morning the usual alarm on the phone rang and everything seemed normal. I turned off the phone and it is currently in the rice bag and has been for about 24-25 hours.

I'm a little nervous because I was looking up stuff online a day after the incident (today) and several articles had said to wash off your phone with fresh water to get out any corrosive materials, like if you drop it in salt water or any sticky drinks. Does the same apply for creek water? And how much longer do I need to leave it in the rice?
Anyone have any advice?

IPhone app for secretly recording video?

I'm trying to find an app that will record video secretly while the phone is asleep. I.e., I want an app that will allow the phone to have a black screen and require the passcode lock to be entered while at the same time record video. There are other apps that record while the screen in black, but if someone grabs your phone and hits the home button, you're found out. Has anyone seen such an app?

Will my iPhone be replaced with the latest model?

The sound on my iPhone is broken and it can't be repaired. The man at the genius store said to replace my phone would be 200$ but will it be replaced with the latest model of iPhone or with the model I have? (I have a 4s) I didn't think to ask and don't really want to drive down to the apple store just for one question.

Added (1). my warranty is up and we canceled Apple Care or whatever it's called.

Android to iPhone, is data transfer possible directly?

The generation of tablets has improved over the years so instead of a netbook or small laptop, my friends wants to get a tablet

But the only issue i have, is there a way to transfer media data between android tablet and iPhone. Some sort of itunes client on your Android tab.

Or any other solution that will make it work, will help
