I dropped my iphone in water, now the screen is black?

I dropped my iPhone in a cup of water, and i got it out the second it happened. At first it was working fine, but then the screen was flashing to a white screen and then the screen turned black. I tried to vacuum method and the rice method, and my phone started working again that day. It was working fine until later that night, where the phone just went into a blank white, and then it just turned black. Now, it hasn't turned back on but it vibrates from calls or texts. I have it sitting in rice and salt now, but I'm not sure what that will do at this point.

I'm having trouble syncing music?

I just updated my iPhone software. It erased all of the music and apps from it, which I was aware of. Then, I tried importing the apps and music from iTunes to the phone, but it's not working. Any suggestions?

Added (1). When I try importing music, it simply does not import. It says that it is syncing, but there are no changed results.

Added (2). Also, after updating the software, my phone turned off and I couldn't turn it back on for quite a while. It started working again this morning. There's also no service, which is another problem of mine. I lost service after updating the software.
