I have an original iPhone running iOS 3.1.3. I want to be able to sync my notes using my google account through Microsoft exchange. I can't seem to find the option to sync notes in my google account in iOS 3.1.3 settings. Is this a limitation of iOS 3? Was google account notes syncing through Microsoft exchange introduced *after* IOS 3? If yes, are there any hacks to enable notes sync in iOS 3?
