Why isn't my instagram working? - 2

My friends account got disabled as she posted an inappropriate photo of her breasts several times. She tried logging into that account on my phone app (Instagram) since then I have no been able to log into my account as it keeps coming up "account disabled" I have tried logging into a few friends accounts on my phone and the same message appears. I have logged Into my account via the Internet explorer and asked a friend to log into my account on his app and it works like normal. So I don't understand. My lock button is broken on my iPhone so restarting my phone is impossible, as an alternative I switched it to airplane mode and then back on. I have deleted and reinstalled Instagram 7 or 8 times now and the same problem is persisting. My account is not disabled as it works on every other phone but mine, what can I?

How to get mp3 downloads onto my iTunes, so they get on my iPhone?

So I know this has probably been answered and is very popular as a question, etc. But I can't find any help and have no idea how to do it. It's not the fact tht I'm trying to swerve out of buying my music because All of my music is bought, but the song I wanna buy is NOT on iTunes, and I really want it on my iPhone. So I tried to drag the song in mp3 format into iTunes, that worked, but now it won't sync it on to my iPhone, even thought it DOES play on my iTunes, it just won't sync.

It's so annoying they don't have the song I wanted to buy!
Any help would be nice.
