Will the "Retina Display" affect developers?

As an iPhone app developer, should I take some steps (especially for graphics) to make them look correctly on iPhone 4 "Retina Display" or 开发者_StackOverflowis there no such an issue?

Thanks for your help and time.

If you're not using vector graphics you're going to want to make provide high res versions of all your images, otherwise it will look pants on the new display.

Other than that I don't think you'll need to do much else.

Use vector graphics so everything scales beautifully on every device.
