I think I accidentally downloaded a virus on my iPhone, what should I do now?

I received an email that claimed to be from DHL, and it had an attachment which I opened (not yet realizing it was a scam/virus). The attachment seemed to be blank, and when I searched "DHL scam emails", sure enough there are emails being sent that claim to be from DHL.

My question is, how do I uninstall whatever I opened? (This is on an iPhone 5 with iOS 7). Is there anything else I should do?

Free music apps or downloader?

I'm looking for something like iTunes where I can listen to music on road trips (when I don't get service) but for free and legal on the iPhone 6 any suggestions?

Definitions of types of people?

Can someone define the meanings of-
Hipster
Indie
Vintage
Skatergirl/boy
Grunge
Emo
Goth
Basic white girl
Tumblr

I got called 'try hard' to be hipster and I was like what? Then I saw the other labels/categories people give others. I would say I'm more individual compared to others, and I know thats 'indie' if I was to labeled. But i just wanna know what they are thanks.

Dropped iPhone 5 in the toilet, still works?

I dropped my phone in the toilet this morning (oops) minutes before I had to catch the train for school. It was in there for literally a second or two, not more! I dried it with a towel and my hair dryer on the lowest setting (I now know that was a stupid idea).
As far as I know, it's still working properly, but I'm at school and can't put it in rice or anything.
Should I worry about charging it or plugging my earphones in?

How much will the iPhone 6 be on Feb 15th 2015?

That's the day I get an upgrade and it's my birthday (that's my 2year upgrade)

I want to upgrade to either the iPhone 6 or Samsung Galaxy s5 but I'm thinking more towards the 6 because I wouldn't need to learn a whole new system, reflow load apps and rebuy music. I really don't want anything else as a present on my birthday and my phone right now does when there's like 50% telling me I need to charge it. I don't get it and the 2 year contract is $199.99

Would the 2 year contract be cheaper on my birthday?

Added (1). also i'd help pay for it if the upgrade is expensive, i'd just save my money
