According to Apple's naming convention for high resolution images

When we provide just name.png, iphone 3 and iphone 4 will display it.

When we provide also [email protected] which has higher resolution than name.png, this time iphone3 will display name.png and iphone 4 will display [email protected].

Here is my question
what if we only provide [email protected]? Ok, iphone 4 will display it.

Can iphone 3 display this image?

Thank you in advance..

No, it can't. Non-retina devices will not find the image and scale it down.

Edit: I've just tested this and apparently on iOS 5, Retterdesdialogs is correct, it is found. I'm not sure when this was introduced, I don't believe it was always the case as I've tried this in the past.

Curiously, letting iOS find the image via naming convention gives much poorer results than if you specify the image manually. I would have expected the downscaling to give identical results, but it seems quite a bit worse.

iPhone 3 can display this image but in low quality because overall pixels get scaled to half size.
