Tarrytown, NY June 6, 2008 -- iPhone users waiting for business-class email, calendaring and collaboration solutions can now use a new tool from the Open-Xchange open source project - the new enhanced web interface for iPhones.

Available at http://www.open-xchange.com/iphone. the Open-Xchange tool features a browser-based iPhone user interface. With no configuration required, it is immediately available to all users of Open-Xchange who have an iPhone.

This is only the first step towards support for the Apple platform. Open-Xchange will announce soon integration tools for Apple Mac OS X iSync. This will be available for free to all who choose to run their own copy of Open-Xchange on their premises and will also become available to the customers of Open-Xchange partners that sell hosted collaboration services.

Open-Xchange offers email, calendar, contacts, tasks and document sharing to provide enterprises with all the tools needed to facilitate communication and efficient teamwork. Users can improve their communication and teamwork with simple, intuitive tools and advanced features, such as smart links between calendar appointments, task lists, contacts, documents, bookmarks and knowledge articles.

"This gives users and developers on Mac OS X and iPhone access to an independent and freely available collaboration solution. The open source version features a preview of the upcoming release of Open-Xchange Server, including special capabilities for the iPhone," said Juergen Geck, CTO of Open-Xchange.
