6670 stolen, how to restore contacts from backup.arc?

[ifad]

Any ideas? None of my friends has 6670 or 7610 to perform a "restore from backup" operation. My last resort could be to go and buy a 6670, but it'll definitively have SW version higher that 4.0..something like I had.

Can backup.arc be restored to a newer SW version of 6670? Please help me!

Thanks
