IPhone 5 got wet, how long do I keep it in rice?

So yesterday my friend accidently spilled some water (out of a water bottle) on me while I was texting on my phone. I reacted pretty fast and got it out of the way, but some water got on the top of the back, like the camera area. (*It was not a lot of water*) I dried it off as much as I could with my shirt, but it was lightly raining so I don't think it got fully dry. I left it on and it was working fine. About an hour later when I got home, I plugged it in to charge and realized no sound was coming from the speakers. They were working on my way home so I guess it was because I started charging it. I unplugged it from the charger right away and turned it off, used a blowdryer to dry the inside and left it in rice overnight. I turned it on this morning and it was working fine, the sound was back. I'm just scared that there could be some continued damage a few weeks from now or something. Should I leave it in rice for a bit longer or is it okay to use now? Any help is appreciated, thanks in advance.

Added (1). EDIT: Overnight, it was in rice for about 8 hours. I turned it on when I woke up and it worked fine. I turned it off and put it back in the rice before I left for work.

IPhone 4 keeps pausing in the middle of video streaming?

So I got this app called Movie Box from Cydia. When I stream movies it will just randomly pause. It's not loading or buffering, it's just paused. I'll have to click the play button over and over to get it started again, which doesn't sound like much work, but it gets to the point to where it only plays for about a second. Any ideas?

Price of a used iphone 4 and 4s?

My friend has a iphone 4 and iphone 4s that were both used for only a year at most. He had a contract with at&t but i have a contract with tmobile. What is the true price I should be paying for both phones since they are used and he bought it through at&t with a contract( meaning he probably did not buy it for the full price)? Thanks everyone!

Added (1). Both phones are 64GB

Added (2). I'm buying the 4s off of him. So how much should he be selling it for?
