I use my iphone calendar to track my business appointments. Is there a way of integrating web calendar with this so I can easily update both, to create a bookings page on my website?

There's no app setup for phones for any of the CC software that I'm aware of.

Can Web calendar synch with outlook calendars, that way I could update form my phone to PC and then upload it (but may be quicker just to retype it!) Surely there must be a way to sync different calendars?

No sorry Mark, I don't believe any of the software syncs with anything else other than S-Drive stuff, which I am not sure how much of anything actually syncs with anything there really.
