I just got a replacement iPhone 4, set it up as stock, no restoring from a backup, and when I synced all my apps some of them, like Epicurious, Engadget, and others are the low-res versions of the app. Yet most of the apps I synced are the high-res versions. I already tried redownloading the apps and while they're downloading they have a high-res icon, but when they finish it goes back to the low-res version. I also just bought The Sims 3 Ambitions from the app store straight from my phone and when it downloaded, it too was low-res. Could it be possible the App Store is mistaking my iPhone 4 for a device with a 360x480 screen? Has anyone else had this problem?
