Strange, i used a small metal cutter to get the camera out, even touch with a metal screwdriver the n97 cam module, but it seems to work ok.

@joerg_rw, i read somwhere that the camera modules of nokia 6720, N79, N82, N85, N96 should also work, but i didn't tested any of those. If i'll find some of those phones second-hand, i'll buy and check the module compatibility.
Also what type of tin will be used in neo900? lead-free or the good old one?
