For SQLBits 8 in April 2011 I published a calendar containing all of the sessions from the conference; anyone could subscribe to that calendar on their phone or calendar service (i.e. Hotmail or Google Calendar).
For the upcoming SQLBits X conference I have done the same again by adding all of the sessions to that same calendar. If you are already subscribed to that calendar from SQLBits 8 then you have nothing to do - all the SQLBits X sessions will automatically flow to your phone/Hotmail calendar/Google calendar (go take a look now - they should already be there).
If you want to get this SQLBits calendar onto your smartphone then the easiest way to do it is add my calendar to whichever calendar service (i.e. Hotmail or Google) you have got synced to your phone and let technology do its thing.
I will keep the calendar updated with any changes to the agenda so, assuming you have subscribed, changes will just propogate to you without you having to do anything. Remember, to save yourself work in the future make sure you subscribe to the calendar as opposed to importing it.
Hope this is useful
UPDATE: I have just discovered an even easier way to subscribe to this SQLBits calendar using the Google Calendar service - simply click this button:
If Google Calendar reports that you do not have permission (as it seems to be doing for some people) then follow the instructions that I provided above. I promise you, the calendar *is* publicly available so if this button doesn't work its Google that is doing something wrong.
