I had it working a few days ago perfectly on the new ipad. I exchanged that ipad today for a white ipad instead of a black one that i had. I restored from icloud but the gmail sync account wan't there so i readded it again but not working.
I have been trying to figure out for the last 4 hours why and have searched and searched. I have tried deleting and adding, no luck. I have tried adding different gmail accounts, no luck. I have tried adding several gmail accounts to another iphone 4, no luck, another ipad 1 no luck, Reset the ipad to orginal factory setting with nothing on there and the first thing i did is try to add my google mail account with calendar and contacts set to sync as well, no luck. The funny thing is the account that i orginally had on the ipad is working perfectly on an iphone that has had it on there for over a year!
I keep thinking it is an issue with google and them adding NEW account registrations to server. Makes no sense, because the same account works on my iphone4. the only common variable that they all have is that they all have tried to be setup in the last 5 hours and all using microsoft exchange with the setting that is outlined by google. If i use add account and use "google mail" it works for my mail and calendar but not contacts. Can't get the exchange optoin to work and have tried on 4 different ios devices with 2 different accounts and no luck.
