I have a jailbroken iphone 3GS with iOS4 (updated yesterday

I found the backup file "document.compta" and replaced it with
my iCompta 3.3.6 backup file. I called it "document.compta" as well.
I found that file using the tool iphone explorer.
Root: /var/mobile/applications/xxxxx-xxxxx-xxxx-xxxxx/documents
My question is how can I import that file to iComptaMobile (I thought it
would go automatically)? And is it possible to sync iComptaMobile and
iCompta by replacing that file?
