Cheers for the heads up.
Both devices are logged into the same account, its odd as everything else syncs fine, i can sync bookmarks, reading lists, notes, reminders etc.
I ditched my pop3 email and changed my email address on icloud, i wonder if this has cocked it up. Both devices were logged out and logged back in with the correct details. I have rebooted both devices, logged out and back into icloud, enabled and disabled icloud for Safari and it still wont bloody work. Being Apple its not like I can edit any config files on a lower level or something. Everything is supposed to "just work" but it don't.
