My background and m开发者_如何学JAVAy icons are all huge, like it's zoomed in 2x. Any ideas why?

Check the images in the app- there should be two sets of images, with one set being at double resolution and suffixed with "@2x". If there's just one set and they seem large, odds are the developer never intended the app to be run on a device that's not running iOS4 (which seems odd, but there it is).

That's because the apps in iOS 4 are targeted for iPhone/iPod 4 which have a resolution of 960 x 640, whereas iOS 3 has a resolution of 480 x 320. Do read about Retina Display of iOS for further details.
