got the 6 this morning, restored form back up of 5s and I've noticed that my gmail no longer pushes. tried deleting and recreating the account..rebooting etc...but nothing. It's currently set up as google account since I have had problems in the past setting up as an exchange account. I noticed that even the option seems to be missing though under Settings - Mail - Fetch New Data for exchange I have Push/Fetch/Manual but for gmail I only have Fetch/Manual anyone else managed to get this to work? or experienced the same problem?
