Technical Preview lost all contacts, how can I get them back?

Technical Preview lost all contacts

Hi,

I downloaded the technical preview the other day but never actually used it as i read about a few problems and as this is my business phone i decided against it.

What i think has happened is the notifications for the update have been pressed in my pocket and the phone has updated to windows 10 preview.

So, i have lost all my contacts and messages as they have not been backed up.

Are these permenantly gone or are they still in the phone?!?

Re: Technical Preview lost all contacts

Hi,

I experience the same problem. However, the contacts are available at people.live.com, at least for me.
It was a vanilla upgrade from WP8.1

And my "Settings" entry is doubled, with the old one not working anylonger.
