Why do that? I imported my contacts from an E71 to the N95 using the Bluetooth "share contacts" function. It took about 15 minutes including the time to figure out how to start the process. People with multiple contacts and email addresses came across quite nicely. I am not a heavy user of contacts on my personal mobile, so there may be some contact attributes that have problems--but all my bases were covered.

Maybe I'll try the Ovi service for a backup method later...
