Hi Henrik,

good job on exploiting the sync quirk!

About the oldest active contact, I'm not so sure though. I don't have  
the device with me but I remember that 3M recycle IDs, giving the  
lowest available ID to any new finger; this means that the lowest ID  
is not always the oldest finger.

Cheers,

St.
