So Safari seems to downscale images that you download, and iCab Mobile and Downloads seem to work the same way. I've also read that Dropbox works similarly. So how can I get retina images (2048x2048 to be used as wallpapers, for example) onto my retina iPad? I don't want to rely on iTunes since it never remembers that I synced my iPad. And is there any way to check image resolution on the iPad? Some app or something? Thanks!
