Greetings!! Had my iPhone 5 for 2 months now and love it. Set up my gmail account using caldav for calendar, carddav for contacts, and exchange for mail. All have been working great ...sync and share wonderfully. My question is this....till recently, I have been able to add sub folders on my phone to organize mail and that would sync with gmail on computer. Now I set a message that I can't do that on the server. The "add folder" button is there, but will not add folder. Tried on iPad, daughter's iPhone 4S . Same thing. Switched email set up to go via Gmail and not via Exchange and it worked fine. Difference being that mail does not push......which was a nice feature.....is this a device problem, an OS problem, a set up problem, or am I in the middle of a new Gmail-Microsoft war?
