So I have the sII and AT&T so I just did the Jelly Bean update a couple of days ago. After some minor adjustments I have nearly everything worked out except the email. No matter what I do I cannot get my phone to auto update when a email comes in. I have checked the settings and it is set to syn every half hour but when you then go look at the account, it says syncing disabled. Previously email would refresh periodically and the little icon would show however many new emails i have. Now it will not do it until I go in and refresh it myself. It's a pain. HELP!!!?!?!?!!?
