I tried to search for this, but did not find an answer. I had my iPhone 4S sync'd to iTunes on a PC. I recently moved to a new MacBook Pro. I don't have the PC anymore. I was able to recreate my music library in the MacBook, and sync the iPad to it. I erased the old music and re-downloaded what I have on the MacBook. My problem is now how to keep all the folders I've created on my iPhone to organize my apps. I have been able to download all the apps to iTunes on my new MacBook. I have all the app files, but if I turn on "Sync Apps" for my phone I am warned that all the apps will be erased, and I'm afraid I will also lose all the folders into which I've organized my apps. I have over a dozen folders with as many apps in each folder, all partitioned by things like Communication, Travel, Media, Games, Utilities, etc. Is there some way to move the folder structure I've created for my apps onto my new MacBook? I've already transferred all purchases from the iPhone to the new machine. I have also created a backup of the iPhone under iTunes. This issue applies to my iPad too. I suppose if a method works for one device, it will work for the other.
