hey I've had the iphone for a while, on ATT and updated to 1.1.2. I followed the instructions on this site how to get it back to 1.1.1 until the point where you type *#307#. It says I need to have the sim turned off but inside. When i did it and slid the emergency button, it didn't have the x that you click when it rings because I think it's because Its been used before. Is that for a brand new one never activated? What's my problem?

THanks
