Setting iPhone App Icon
1. Create the Icon considering the following requirements:
- Image must be 57x57 pixels in size.
- File name must be named "icon.png"
2. Save it inside the your project's top folder(this should normally be along with the project file).
3. Go to Menu's Project->Add to Project... Then select the Icon file. (This is important some simply specifies the filename at the .pList file which does nothing.)
4. That's it, rebuild your project and the icon should now be updated.
