What is the image size limit for iPhone 3G using iOS 4.2?

My app uses an image 4000x2828 pixels, about 2.9 MB compressed.

It runs fine on iPhone 4S iOS 5, but silently stops working on iPhone 3G iOS 4.2.

The app runs fine if I change the image to another one 501x501 pixels, about 900 kB compressed.

Is there a maximum image size or memory limit on iPhone 3G or iOS 4.2 I should know of?

I'm fairly sure the max images sizes for non retina devices (excluding ipad) is 1024x1024. For retina devices and iPad it's 2048x2048.

iPhone 3G has supposedly 128 MB of working RAM; that size of image takes about 34 MB uncompressed (it has to be handled uncompressed). So, while I can't tell you the maximum image size, you could make a test program generating bigger images (start in increments of 100 px) until you get the error.

Edit: you may want to have a look at this thread for a possible work-around.
