I have seen this posted a few times, but with no definitive answer. My iPhone backup is 2.4 GB. When I click to see the apps that are backed up, the biggest thing is the camera--32.0MB, and the rest are all considerably smaller than that. I have no voice memos or reminders, and my camera roll only has one video and a few pictures. I have iCloud Mail turned off, as well as Safari and Passbook. I deleted all of my iMessages (a lot of them had videos/pics I had sent...though I do use iMessage for Mac and haven't deleted all of those). Nothing changes. Any ideas why the backup is so big? Thanks!
