I have recently upgraded to an iPhone 5, I previously had an iPhone 3G. On my old iPhone when I actioned anything in mail such as deleting an email or moving it to a folder when I logged into my PC onto my Gmail account the action had also happened there. It is now very frustrating that I move a lot of emails to the bin on my iPhone 5 but then when I get home to my PC and open my Gmail account all those emails are still sitting in the Inbox as unread. My Gmail account settings are set to IMAP. Can someone guide me through what I need to do to have both my iPhone 5 and gmail account sync actions?
