So I have a gazillion apps in my iTunes library that I'm about to delete to start fresh for the new year. When I select apps and click delete iTunes gives the usual "This app will also be deleted from any iPod or iPhone which syncs to your library" warning. That's a bit scary. I'm thinking that I might get away with deleting all of them if I Transfer Purchases BEFORE I attempt to do any syncing ->But what if your phone is set to auto sync when you connect? I can't stand that iPhone Applications tab in iTunes either. Takes forever to do any kind of organizing in there when you have 400 apps or so. Gotta scroll down the long list and choose what you want to be synced or not one check box at a time. That's why I want to delete all of the apps from my iTunes library first. EDIT1: And let's say I decided I wanted some of those apps back. There is a permanent record at Apple/iTunes so when I search for it in the store using my phone the app will still show as previously purchased even though I deleted it from my iTunes library right? EDIT2: Well I went ahead and deleted all apps from my iTunes library and connected my iPhone and selected Transfer Purchases to iTunes so that the only apps that are in the iTunes library are the ones that were on my iPhone. Copying 328 apps to iTunes. A lot better than the 500 I think I had before. Next up is my iPad. .
