I have actually shot myself in the leg with this. I recently removed MfE account which was used also for Contact sync. And all my contacts were lost. I wonder why this is nowhere emphasized?! Lucky for me I had a couple of days old exported contacts on my phone. I was able to revert back 99% of data. Had to open each *.vcf file in File Manager on my N9 and add it back to phones contacts.

I've learnd my lesson, no more contact sync to online service, it is just too unreliable. So much for the "cloud" .
