iPhone dev: Remove the glossy effect from the application icon
As you probably know, the iPhone adds a nice glossy effect to your application’s icon. It sure does look good, but sometimes it just doesn’t suit your icon. It can be prevented by editing the Info.plist file. It’s easy! Follow me.

Click on one of the lines to make the little plus icon appear. Click the plus icon to add a new line.

Give it a key name of UIPrerenderedIcon.

The value is by default set to String, but we need to change it to Boolean. Right-click the newly created line, choose Value Type > Boolean.

The value has now magically transformed into a check box.

Click it!
And you’re done. It’s as easy as that.
