I've got a number of iPhone apps that are useful - necessary even - on my 3GS, e.g. the Amazon.com app. After installing it the next time I sync with my MBP the app gets copied to iTunes but when I then sync my iPad, iTunes installs the app on the iPad, which I don't want it to do as the app is not needed because I use the normal Amazon website in Safari on the iPad. If I delete the app from the iPad, it gets re-installed next time I sync. How do I stop this? It seems that iTunes syncs any app that is compatible with the device being sync'd. When I look at Apps in iTunes they are grouped by the device(s) they are compatible with, not the device they were (originally) installed - i.e. downloaded - on. Is there any way to configure iTunes to not do this and maintain the apps on a per device basis?
