freenet.de AG Deploys O3SIS' Over-the-Air Synchronization Services to Enable Mobile Phone/PC Convergence

O3SIS SyncML (OMA DS) Data Synchronization products allow freenet customers to wirelessly back up and sync personal data between their mobile phones and PCs

SACRAMENTO, USA, May 11, 2006 - O3SIS AG, a leading provider of personal mobile applications and Over-the-Air (OTA) data synchronization (DS) technology for first tier mobile network operators, today announced that freenet.de AG has rolled-out new data synchronization and backup/restore services powered by O3SIS.

freenetMail Sync combines O3SIS advanced, end-to-end SyncML (OMA DS) and Backup and Restore over-the-air data synchronization products allowing freenet subscribers to transparently sync contacts, calendars, and tasks between their web organizer, mobile phone and PC.

"With the increasing amount of personal and business data stored to phones and PCs, O3SIS and freenetMail Sync now make sure that customers are always up to date and their information is safeguarded, all the time," said Kai Schulmann, Head of product management Convergence, freenet.de AG. "Now our customers can easily experience the benefits of media convergence and manage their personal data both on their PC and on their mobile phone and web organizer - eliminating the dependence of data entry using unintuitive and small keypads."

"freenet subscribers can enjoy more productive data and contact management as well as peace of mind," said Dirk Dörre, CEO and CTO at O3SIS. "Prior to freenetMail Sync, customers would have to re-enter all of their data if a phone was lost or damaged. Now, all data is kept up to date and instantly transferred to the new phone with a simple push of a button."

O3SIS SyncML (OMA DS) data synchronization and Backup and Restore products are key components of the company's Unified Mobile Applications (UMA) platform, which provides Over-the-Air data synchronization, a full-featured address book, mobile device backup/restore, and mobile personal information management (PIM) functionality including consumer push e-mail. UMA enables operators to roll out multiple value-added services from a single, high-performance platform, significantly reducing system complexity and maintenance costs. O3SIS' UMA products supports Over-the-Air synchronization on more than one hundred different devices from all leading handset vendors.
