Hi there!

I recently updated my iPhone's firmware, and I saved my /User/Library/SMS/sms.db file.

The problem is, when I restored it, I can't send nor receive SMS's anymore.
But then I found this thread.

I overwrited the sms.db file, and I changed the owner and group using chown and chgrp respectively.

But still, I can't send SMS...

What can I do to make it work?

Thanks in advance

Ok, I eventually find out what I was doing wrong...
Apparently, the file you have to replace is /private/var/mobile/Library/SMS.

Everything is working fine now.
