Just got one of these as an upgrade and I'm in the process of transferring my data across from my old HTC Desire S. I'm using Mybackup pro version btw.
Whilst all my calendar entries have transferred across I now seem to have entries for sodding everyones birthday on facebook.
Now the calendar on the Desire had the option of unticking facebook but I can't see that on the One. I've got PC sync and a few other calendar options but not a dedicated Facebook one.
Any ideas how I can clear the Facebook calendar entires?
