The default icon, in a iPhone projects, has a shine and gloss effect by default. If you want create your effects in the icon image, you must disable this effect. To do it, you need to add a new property in the info.plist file. The key of this property is UIPrerenderedIcon and it needs to be set to YES. If you are editing the info.plist XML, you can add it using this new tags

<key>UIPrerenderedIcon</key>
<string>YES</string>

And then you`’ll see your icon without this effect.
