Funambol Inc. announced the availability of its new free Funambol plug-in for the iPhone. The Funambol plug-in enables users to easily and freely sync their address book from an older phone to an iPhone 3G over-the-air. It also enables users of the iPhone 3G (as well as original iPhones and iPod Touches that have been upgraded to 2.0) to wirelessly back up their contacts for free, and to easily keep their contacts in sync with popular webmail systems, and email clients such as Outlook and Thunderbird.

The free plug-in, which was listed as a top 20 cool third party app for the iPhone 3G by IDG News Service, can be immediately downloaded from the Apple App Store, from its Productivity section.

“One of the first things that iPhone 3G users want is contacts on their phone and they don’t want to type them in,” said Fabrizio Capobianco, Funambol CEO. “The Funambol plug-in makes it really easy to migrate contacts from an older phone, webmail system or email client. Plus it freely backs up contacts to a server without a cable. It is easy to see why the Funambol plug-in was just named as one of the top 20 third party iPhone apps.”
