Answer 1

You just need to remove your account? Your question isn't to clear. But if you mean you just need to removed your information and such from that account you need to have your password and ID. So heres what you have to do... This is if you have iOS 7, I believe it is pretty similar with iOS 6.
1. Go into settings..
2. Go to iCloud
3. Scroll all the way down and you'll see Find my iPhone, you're going to want to turn that off.
4. After you turn that off you can delete your account
Both times iOS 7 asks you for your password each time for the account. So make sure you have that! And on a side note, make sure that you turn off the "Find my iPhone" feature. It is very important that you do that if you are planning to sell it or your work needs the phone back. The reason is if the feature isn't turned off and you don't remember the password for your iCloud account, it is nearly impossible to reactivate the phone because your iCloud account is permanently linked to it. This makes it like I said, just about impossible for someone else to use the phone. It is one of Apples best security features and honestly it works fantastically.
Next if you want to completely erase the iPhone all together so that you have no information on it you do the following
1. Settings again.
2. Go to General
3. Scroll all the way to the bottom and select reset.
4. You're going to want to select "Erase All Content and Settings"
5. iOS 7 should inform you that doing this will erase all content on your iPhone. You're going to want to select yes, then I believe it will ask you once again for your iTunes account password. Put it in and it will start to reset and erase your iPhone.
After that you should be in the clear, just make sure you post any other questions. I'm not the best Apple enthusiast here but I do know most of my stuff very well. Other people may know some things I might not. Hope I helped! Good Luck!
