^ I just made that Yelp icon (red one) and the phone put that half crescent shine on it.
How do you get rid of that?
You have to go the app's folder located /var/mobile/Applications/ <-here find the Yelp folder.
Then go into the app and open the info.plist and find and change this line to "true", like this:
<key>UIPrerenderedIcon</key>
<true/>
