Apple and Cisco Systems have used the Macworld Expo in San Francisco to release a version of Cisco's WebEx Meeting Center collaboration application designed to run on Apple's iPhone 3G and iPod touch.

IPhone and iPod touch users will be able to join a meeting with the click of a button; the connectivity is enabled through 3G or Wi-Fi networks. There is no charge for joining a meeting.

To start using the service, users must download the Cisco WebEx Meeting Center application from the Apple App Store. Once this is completed they can join any meeting by clicking an invite link.

Users will not be able to upload their own presentations, but will be able to view others, according to the firm.

IPod touch users get a slightly different experience in that they can join a meeting over a Wi-Fi connection, but will need to get the audio portion from a phone.

Apple has been able to show off a number of recent productivity applications for its handheld devices, including the newly announced HP print application. This lets users send images stored on their iPhone or iPod touch via a wireless connection to an inkjet printer.

Full details of the WebEx deal are available at a dedicated WebEx/iPhone FAQ web site.
