Contacts imported correctly then instantly deleted!?

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Export vcard (all phone book) from Sony 905
2.Send via bluetooth to Samsung Galaxy S
3.Import using vcardIO

What is the expected output? What do you see instead?
The progress bar stops just short of the end.  If I exit and view my contacts I 
can see that the contacts have been added, all fine pictures and all!

The problem is that the contacts then slowly get deleted.  Over the course of 
the next 30 seconds you can watch all the contacts dissappear again! I'm 
assuming it's the vcardio service which is removing them after adding? Perhaps 
thinking they are duplicates?

What version of the product are you using? On what operating system?
Galaxy S.  Not sure which app version.

Please provide any additional information below.
We got two Galaxy S phones at the same time.  I imported the phonebook onto one 
with no problem (from lots of separated vcard files). The other where all 
vcards are in one file exhibits this problem.
