Does having no access to the itunes account affect the use of an iphone?

My friend wants to buy a second -hand iphone online (which i think she shouldnt do- its risky) and it says in the description that it is associated with an itunes account that there's no access to, because the person selling it also bought it second hand. She asked me about the itunes thing so i told her I'll find out, if she bought that iphone could she use t normally just not use the itunes?

My iPhone got wet and now it won't turn on?

I dropped my iPhone in the shower today for about 2 seconds, and needless to say, it swallowed some water. Panicking, I dried it off the best I could with a towel. It had run out of charge, so I wasn't sure if it was working or not. Being the dumbass that I'm, I decided to plug it into the charger, and it showed that it was charging. Figuring all was good, I left it there for a while, but when I came back to check on it, I realized it wouldn't turn on. I noticed that the screen and the camera had gotten foggy, and by this point, I realized that my iPhone was in trouble. I quickly removed the SIM card and placed it in a container filled with rice. I put it in rice about three hours ago, and when I checked just to see if it would show any sign of life, nothing happened. I noticed, however, that the fogginess had basically disappeared. I'm just really impatient and I don't know what I should do! Is there anything else I can do to save it?
