iOS apps with iCloud backup

The following apps automatically backup your data to iCloud (or is it Game Center?) - progress and saves are transferred to new devices:

• Cut The Rope
• Infinity Blade 2
• Temple Run (backs up high scores but not purchased powerups)
• Tiny Wings

Notably, the following apps do not:

• Angry Birds
• Angry Birds Seasons
• Angry Birds Rio
• Angry Birds Space (all last checked 1 Oct 2012)
• Gravity Guy
• Trainyard
• Trainyard Express
• Where's My Water
