thats the point metsuri, dual sim would be more than great!
btw in facebook is an online wishlist... search jolla mobile
so my wishlist from jolla santa is:

-n950 like device, not bigger
-dual sim (@ same time) for work and private
-powerful battery couse of the n8 cam with autofocus
-mobile is able 100% to run android apps
-camera lens cover! protects and hw activates, just like by n900
-hw buttons (vol, pwr, cam, home!-note how difficult is f.e. by using sygic navi--power, phone, close it, than home)
-rgb function based front led
-replaceable battery
-not made for NASA, enough is 1G/720p/4"
