I've got a Nexus One on which I'm running Cyanogen 6.1. I use the stock email app for connecting to work exchange. I've got it to setup to sync with it manually because I don't want it to waste battery syncing when I'm not working and not interested to read email. It would be handy to be able to turn email sync (even set it to push) during office hours but keep it manual outside office hours. Does anyone know of any way of doing this? Perhaps with a command line switch on the email app? I'd prefer to stick with the stock app for this if possible.
