Apple deleted my iTunes account. How do I get it up an running again so I can update everything?

Whenever I try to update my apps on my iPhone, it says this: "This iTunes account has been disabled for security reasons." But yet it remains on my iPhone. I try using my brother's account, but it still has my info on it. If there is no solution to get it running again, how do I delete the info from my iPhone?|||How you would delete the info is by going on to iTunes on your PC or iMac, and going to the store, logging out and then logging in on your brothers account, or making a new one of your own, this will then automatically send the new info to your iPhone and you will no longer be stuck with you old disabled account details.
