Zimbra, a Yahoo company, and the leader in open source, next-generation messaging and collaboration software, today announced general availability of Zimbra Mobile for iPhone 2.0.

Zimbra Mobile provides over-the-air (OTA) two-way synchronization of e-mails, multiple calendars and contacts between user mailboxes and mobile devices, and enables seamless “push” e-mail service for all versions of Zimbra Collaboration Suite (ZCS) Network Edition Standard or Professional, including the most current version, ZCS 5.0. Zimbra Mobile for iPhone 2.0 software allows iPhone users to maximize their business functions on the iPhone.

Complementing this Apple’s recently added support for Microsoft Word, Excel, and PowerPoint, PDF, JPEG and iWork. Additionally, Zimbra Mobile for iPhone enables OTA photo-sync, so photos associated with iPhone contacts will sync with the Zimbra address book as well.

“We believe the iPhone is a great device for both personal and business use, and we are dedicated to providing iPhone users with mobile support to match iPhone’s enterprise class capabilities,” said Satish Dharmaraj, Yahoo! VP and Zimbra co-founder. “We’re demonstrating our commitment to the Apple community by enabling Zimbra Mobile with the best iPhone enterprise support.”

“We’re very excited that Zimbra is leveraging Apple’s support for over-the-air sync on any iPhone or iPod touch with 2.0 software,” said Jon Enos, CIO, Franklin and Marshall College. “The iPhone and iPod touch are sure to be very popular among students, faculty and staff and we look forward to rolling out Zimbra Mobile capabilities to iPhone and iPod touch users across campus.”

The newest version of Zimbra Mobile for iPhone for Zimbra Collaboration Suite 5.0.9 adds support for synchronizing multiple calendars and address books, and also takes advantage of the latest Zimbra Server and iPhone software enhancements to further optimize push email performance.

Support for iPhones running 2.0 software is part of a wide range of smartphones Zimbra Mobile already supports, including Microsoft Window Mobile devices (PocketPCs and Smartphones), Palm Treo series, Nokia E series, BlackBerry and other devises running third party clients.
