(keitai-l) social networking interface

Can anyone recommend a camera-phone for social networking?

  I am currently meeting a huge number of people on "business" and, 
having a dire memory for Japanese men's names, need to take a quick 
snapshot, get it into an address field and have contact details entered 
as quickly as possible. This is an interface issue as much as a 
hardware issue - does any one have any recommendations for a handset 
with a slick interface for contacts and the like?
