So I'm having issues with syncing for the first time. I have an iphone but I'd guess the same would happen for ipod touch. So I have a couple of applications I'm installing frolm my iphone's AppStore. Then, when I click on 'sync' in iTunes, it syncs ALL applications, even though I did not change. So let's say I had 10 applications already on my phone and they are already synced on my PC/iTunes. Then, I install a new application on my iphone (not on itunes) and I click on sync in iTunes, it will sync EVERYTHING again. Not only the new app. It did NOT use to do this before! What am I missing?
