Create a SQLite3 database via import of XML file created by FritzBox WLAN Router or FritzFon App. Another option is convert your contacts from iPhone via vCard.vcf export out of our iCloud contacts. This could be converted to a xml and than imported to a SQLite3 database. This option shows also addresses, birthday and note from your contacts. This is a private project and have nothing to do with the German company AVM or the US company Apple!
