I am just curious and want to ask, how many have you have purchased something from itunes? I buy and get free iphone apps and music all the time. I was thinking it is $0.99 here, $1.99 there, free at times. It doesn't seem like much but over all it does add up! I am not complaining, far from it, but am wonder how many others are like me and like to get that 99 cent app or song.
I had problems, the two things that worked for me was stepping away for even 5 to 10 minutes (longer better) and going to a empty conference room and reading it out loud. You can hear your mistakes, read slow and listen to what you are saying. After a while you can train yourself to read slow and aloud but in your head. It helped me. Good luck, I can relate to this problem.
