We are in the process of updating our popular iOS app, Gift Suggester (itunes.com/apps/giftsuggester), for the upcoming iOS 7. Gift Suggester takes a user's selections on occasion, personality, recipient, and category and returns a list of awesome gift ideas! iOS 7 packs major design changes and we want to be ready! We need a new icon that reflects the new flatter iOS 7 look. You can see some examples of the newer icon style here: http://www.apple.com/ios/ios7/design/
Apple has provided a sort of template with a "golden ratio" that might be helpful. Using this is not required, just food for thought. You can see it here: http://appicontemplate.com/ios7
You are free to be creative but having a gift in the icon might be a good idea. The color scheme of the app is shown in the attached picture.
The icon will need to be 1024x1024 in its largest form and then look nice at Apple's specified icon sizes.
EDIT: Please try to include how to icon would look on the iOS App Store as many have already done. Thanks!
EDIT 2: Some of you are including shadows, iOS 7 icons move away from this so please try to avoid these and go for a flatter look.
