I use multiple iPads at work, all logged into my account. I notice sometimes when I download an app on one device it also downloads to the others, though not all the time. 1. Is there a way to synch settings for Mail, and and other system settings across devices, so when I make a change on one it is synched to the others? 2. Why do apps sometimes get downloaded to all my devices after downloading them to one device and sometimes they don't? 3. Is there a way to synch home screen layouts? Thanks.
