My wife bought an ipad and has installed apps to it. She loaned it to her brother who put apps on it under his itunes account. I have an itunes account as well and want to use the ipad. She got a mac so she doesn't use it anymore. I want to use it and have her itunes password and synced it to her mac. I don't have her brother's account. I don't care about syncing his apps, but I want to delete his apps from the ipad. How can I tell which apps on the ipad correspond to which itunes account? I want to delete his only, keeping my wifes, but don't see a way to tell the difference. Is there?
