Ok, I have "permission" from AT&T to unlock my phone. But am leary to do it. Just for the pain factor. I have backed up the phone to my phone and wonder after I reset it it how much do "I" have to do. Will all my email account re-create or will I have to manually do it. I know most everything else will work but how many things do I have to re-create? Thanks in advance.

You just put in the code, it didn't affect anything else on my phone when I did it.
