Not today or tomorrow :-) I haven't decided to buy the miniSD card yet and also there is some possibility I might get dead N770 from some board member here so I'll probably wait until I get it (to have spare black case and to make trial run on killing the mmc slot :-) Also I currently don't have pressing need for 4GB yet. Still I'd like to do this mod just for the sake of doing it so I'll eventually do it anyway but not now.

Actually I will open my device soon and try empty adapter to see how it will fit but I won't cut/solder anything yet.
