iphone - Retina display and [UIImage initWithData] -

I need to start images from raw data downloaded from a server that has an image based on the type of iPhone client Provides the correct size of

I know that I should set scale value 2.0 on the 640x960 display, although this is only a readable asset and can not be set during init when using initWithData.
