re: Why didn't they fix the issue with the wallpaper not fitting on the iPhones before they updated??!!
You would have to contact Apple through their normal ways of through their support site to ask them what you wish to know and get the answer from them. Are YOU sure you are using the proper pixel sizes for the iPhone version you have so that your WP is fitting properly?
I might suggest that if your user name is indeed your real email and you don't want problems with anybody contacting you, You ask iMore to change your username to something other than an email address. Just a friendly word of advice.
