instead of opening a new thread, i'll post in this

i just received my n900.

i imported all the contacs from my sim-card to the device and found that one of the contact has his name written uncorrectly (hermes isnt finding his details on facebook either because of this)
also, i want to change some contacts details.

how do i do this? it seems the n900 doesnt feature any ways to edit the given information for contacts. please help!! :>
