Find My Iphone Problem with acct setup.

Got the app Find My Iphone today. I setup my wifes account first and it was smooth sailing. I go to setup my phone and I get a totally different screen when I go to the add account screen for mobileme. I get a screen that has the Name: Address: Password: and Description on it. Is this because I had a mobileme trial account years ago? I have no freaking clue what the account details were. I canceled that account before the grace period was up. Can anyone help me? I tried entering my apple id and password but it doesnt work.

Problem solved, you need to have the latest software update on your phone in order for this app to work.
