The iPhone app is dubbed IBM Lotus iNotes ultralite, and is built on the Lotus Domino Web Access infrastructure. Lotus iNotes allows users to access e-mail, calendars and contacts directly through the Apple iPhone Safari browser.

The IBM Lotus iNotes ultralite software download is available at no extra charge to users who have a Lotus Notes software license and is also included with IBM's new Lotus Notes software 8.0.2, which uses 20 percent less memory than the previous version.
