I dropped my iphone in the sink and now the sound isn't working?

I dropped it in the sink while the water was running for like 2 seconds. I took it out and everything is fine, except the sound isn't working. I put it in a bag of rice. Is there anything else I can do? Do you think its permanently damaged or will I just need to wait it out?

Downloading an app for my iPhone?

I tried to download stumble upon to my iPhone 5s and it hasn't finished downloading and it won't let me delete it from my screen, it has been like this for 3 days

Am I spoiled for having these apple products?

So I'm 13 years old. I currently have an iPhone 4s that I bought last year from eBay secondhand, an iPad that I got the year before last as a Christmas present and a iPod 5 that I bought with my Christmas money last year. I have been saving my money for a while now and I hope to get the new iPhone when it comes out, with that money. There's also a possibility I may be getting a MacBook Pro from one of those trade in secondhand stores at Christmas.
Though I'm very grateful for all of these things, I feel as though I'm spoiled and shouldn't have them at my age. Am I spoiled or just fortunate and grateful at that?
