I have corporate calender and I'm running sapphire. I do run better widgets and tap on the calender part, menu, more,calenders, click on the ones you want your calender to sync with.
Of coarse you need to go into settings first and set up your corporate calender to sync.
Did you install CC after flashing or was it there on it's own?
all I did was install the google apps, after installing sapphire, then market fix. Then went in to settings, sync and added corporate calender info, then added my facebook info and it was all there. I just tap on my calender in B. Widgets and they are all there, but I do go into settings and shut off google calender since I do not use it.
I get my mail and everything.
