iOS Retina Display: Does "@2x" support jpeg as well as png?

Question

Can someone please confirm/deny whether the iPhone retina display supports the "@2x" filename scheme for jpeg as well as png?

Thanks,
Doug

Answer 1

yes it does. No difference on that.

Answer 2

According to Apple's documentation

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImage_Class/Reference/Reference.html

UIImage supports JPEGs and also automatically applies the @2 name modifier when running on a device with Retina display.
