Sounds on Iphones messed up and not working?

Ijust got an Iphone 5s 2 days ago and the sounds just stopped working all of a sudden? I turned it off over night them work up andtried a ringtone, it worked then tooka phone call then tried the ring tones again and they didn't work! Music, games, ringers, videos, everything that needs sound won't work. Its not the orange button on the side either, and all the volumes are up. I went to all the ring tones and the all just vibrated. How do i fix this, its driving me insane.

Somethings up with my iphone 5S?

I was putting a cover onto my new Iphone 5S when it switched off and then switched itself on again, but when it did - the screen was a different menu all together. The phone was bought in Hong Kong - but in a licensed Apple store so the new menu that has popped up is all in Chinese!

I have no idea what's happening or how to switch my phone off, I've seen this happen before to my brothers ipod but his was an intentional jailbreak - I'm so scared I've already ruined it when I only got it yesterday!

Accidentally bidded on something on EBay?

This is going to sound ridiculous and stupid but I thought one of my devices wasn't working because when I put a cartridge in, it said it couldn't read it.
So I stupidly bidded on one on EBay because I thought it was broken but I tried again and forced the cartridge in and suddenly it started reading and playing it.
I will probably get out bid anyway but I bidded when there was only 1 hour left so there's a chance I might win it.
Is their any way to unbid? I can only access EBay on my smartphone at the moment though. So if you know how to do it on a smartphone (iPhone) please tell me how.
