IBM has expanded Lotus collaboration software and has unveiled an enterprise secure mail for Android, the iPhone and Nokia Symbian smartphones.

IBM said that it plans to expand its enterprise mobile messaging offering in a future release of Lotus Notes Traveler, which will include mail, calendar and contacts support for versions 2.0 and 2.1 of Google’s Android mobile operating system.

Lotus Notes Traveler provides two-way, over-the-air synchronisation of information between Lotus Domino data and mobile devices.

In addition, IBM has unveiled a new application for the iPhone called IBM Lotus Notes Traveler Companion, a plug-in to view encrypted mail on the iPhone. It allows Lotus Notes users to view encrypted mail such as confidential business and personal data on the iPhone. The application requires Lotus Notes Traveler 8.5.1 software.

IBM’s partnership with Nokia has led to a spectrum of collaboration capabilities on Nokia’s smartphones that include IBM Lotus Notes Traveler, IBM Lotus Mobile Connect, IBM Lotus Sametime and IBM WebSphere Portal, XPages-based applications built with IBM Domino Designer developer software.

A future version of Lotus Sametime software for the Nokia Symbian smartphone devices is planned to offer users presence awareness and Lotus Sametime Unified Telephony click-to-call capabilities in the native address book on the device.
