iOS web app splash screen sizes

Always hard to find those splash-screen sizes for web apps on an iOS device;

• iPhone 3G/3GS : 320x460
• iPhone 4/4S : 640x920
• iPhone 5 : 640x1069
• iPad 1/2/mini portait : 768x1004
• iPad 1/2/mini landscape : 1024x748
• iPad retina portait : 1536x2008
• iPad retina landscape : 2048x1496

They differ from the native app splash-screen sizes because of the top-bar.
