I want to know since I haven't found anything in my brief time surfing the web on this particular topic. Reason I am concerned was that I experienced a very worrisome glitch running iOS 7 GM where when after a couple of days of running it fine I encountered a serious problem when I decided to change the wallpaper to the red hue one (the one I imagine comes by default on the pink iPhone 5c) and when I went to unlock the phone the next time after I couldn't slide nor interact with my iPhone at all. No matter that I followed all the necessary troubleshooting steps like shut down the device and restarting it by holding the power and home buttons. Decided to restore from iTunes and downgrade to iOS 6.1.3 my iPhone 4s because I didn't had the extensive time to continue troubleshooting this issue further and wanted to corroborate that anyone else has experienced this ?
