The QtMobility APIs are placed into the QtMobility namespace. This is done to facilitate the future migration of Mobility APIs into Qt. See the Quickstart guide for an example on how the namespace impacts on application development.
Versit API provides a set of methods to parse/read (QVersitReader) and encode/write (QVersitWriter) Versit ® documents such as vCards (http://www.imc.org/pdi/). Currently QVersitReader and QVersitWriter support reading and writing vCard 2.1 and 3.0 formats.
Versit API also provides utilities to import (QVersitContactImporter) QContacts from Versit documents and export (QVersitContactExporter) QContacts to Versit documents.

// Create the input vCard QBuffer input; input.open(QBuffer::ReadWrite); QByteArray inputVCard = "BEGIN:VCARD\r\nVERSION:2.1\r\nFN:John Citizen\r\nN:Citizen;John;Q;;\r\nEND:VCARD\r\n"; input.write(inputVCard); input.seek(0); // Parse the input into QVersitDocuments // Note: we could also use the more convenient QVersitReader(QByteArray) constructor. QVersitReader reader; reader.setDevice(&input); reader.startReading(); // Remember to check the return value reader.waitForFinished(); // Convert the QVersitDocuments to QContacts QList<QVersitDocument> inputDocuments = reader.results(); QVersitContactImporter importer; if (!importer.importDocuments(inputDocuments)) return; QList<QContact> contacts = importer.contacts(); // Note that the QContacts are not saved yet. // Use QContactManager::saveContacts() for saving if necessary // Export the QContacts back to QVersitDocuments QVersitContactExporter exporter; if (!exporter.exportContacts(contacts, QVersitDocument::VCard30Type)) return; QList<QVersitDocument> outputDocuments = exporter.documents(); // Encode the QVersitDocument back to a vCard // Note: we could also use the more convenient QVersitWriter(QByteArray*) constructor. QBuffer output; output.open(QBuffer::ReadWrite); QVersitWriter writer; writer.setDevice(&output); writer.startWriting(outputDocuments); // Remember to check the return value writer.waitForFinished(); // Read the vCard back to a QByteArray output.seek(0); QByteArray outputVCard(output.readAll());
