@boggiano: The problem is I don't know the data of all the counters or options.
If you want to help:
-Activate the log XML in the settings
-Update the data (menu - Aggiorna)
-Close the application

Send me the file /home/user/.vodafone190/vodafone190.log
Before sending the file open it and remove all the personal data (username, password, number, ...)

You can send the file to sakya_tg@yahoo.it
I'll look at your data and fix the problems.
