IBM has unveiled a sneak peek of its new Lotus iNotes, a Web app client for its Lotus Domino messaging server to bring email, calendar, and contacts to iPhone. The move fulfills rumors of customized iPhone support for Lotus Notes and demonstrates IBM’s evolving interest in Apple within the enterprise.

Planned for delivery later this year, Lotus iNotes is built upon IBM’s existing Lotus Domino Web Access infrastructure. The company’s Web site invites users to “bring the enterprise to your Apple iPhone” and says the software will deliver a “rich Apple iPhone user experience.”
