Thanks to everyone for getting this to work!

Mercedes Audio 50 APS seems to work (I have added it to the wiki page), although I have to tell it to "Import Contacts" -- it doesn't seem to find them automatically. I may experiment some more to see if this is different with other phones.

By the way, looking at the hcidump output in wireshark I noticed a bug: in some circumstances the vcard has an N: line with only one ";". This is wrong -- every N: line must always have exactly four semicolons. I haven't been able to work out what circumstances cause it -- I have some contacts which are formatted like that but I haven't been able to create any new ones which format like that.

Which code creates the vcard itself? Is it part of this project or part of the N900 contacts code?
