I only get 6GB of memory every month, how do i conserve it?

Okay so i have a wireless hotspot on my iphone. I get 6gb everymonth and i only want to play runescape. Yesterday was my first day using it and i already lost 1GB ( and i know runescape can't take that much).Im thinking it was because while i was playing runescape on my computer, i was watching netflix on my phone. I have sprint btw.

One laptop can connect to our home Wi-Fi network but no other devices can connect?

We recently set up a wireless internet connection in our house. One laptop can connect to it (the one I'm currently on) but no other devices can connect to it. It says our "Network Security Key" is mismatched. I have tried typing in all the different codes on both the router and modem on both our second laptop and an iPhone 5. How can I fix this?

Iphone 4s dropped in toilet DX

So here's how the story goes.
My sister has (had) and iPhone 4s. Well, it went into the toilet.
At first the only problem was that the LED light wouldn't turn off, and there was no sound (except for when she made calls and the ringtones were working. But it wouldn't play music.)
So we put it in a bag of rice and hoped for the best. Well, it got worse.
Now the phone is saying there's no service, and won't hold a charge. The LED light went off, and the screen works fine and everything. But still no sound.
What can we do? Will Apple do anything like maybe trade it out for a refurbished one for an extra cost?
Or will we have to buy the phone outright? @_@ We have sprint, and are certainly not eligible for an upgrade yet. (also we have no warranty on the phone. But i didn't have a warranty on my i-pod and they still did something for me.)
Any help is very appreciated.
