Oracle and IBM will both work with Nokia to bring corporate e-mail and calendar applications to a user's inside pocket.
The two companies made their respective announcements independently at the 3GSM World Congress in Cannes.
Oracle and Nokia launched a joint initiative to extend Oracle's Collaboration Suite messaging application to Nokia phones, while IBM and Nokia said they planned to make Nokia handsets work with IBM's WebSphere middleware and its new Wireless Enterprise Delivery Environment.
Nokia's handsets, including the 6800 messaging device, the 9210 communicator and several phones running Symbian's operating system, will support both Oracle's and IBM's applications.
Initially, both Oracle and IBM will focus on e-mail, calendars and related features, they said.
Both companies also plan to bundle their products with Nokia handsets and offer complete mobility packages with the company.
Oracle does not expect service providers to offer mobile services based on Collaboration Suite to the masses.
The product was meant for enterprise users who want to go mobile, vice-president of Oracle 9i marketing, Rene Bonvanie, said.
"The first opportunity that we will pursue is to go to service providers to deliver this to their enterprise customers," he said.
An enterprise user could run the service in-house, but "playing mobile phone operator really is not their business," Bonvanie said. "Users are looking at operators to solve the problems."
Oracle launched Collaboration Suite, its answer to Microsoft Exchange, in July last year. By October, the company said it had about 300 Collaboration Suite customers. The first customer pilots with mobile devices are planned for the second quarter in the U.K..
Oracle and IBM aren't married to Nokia. Both are also looking at other handset makers. Oracle is in talks with Siemens and Motorola. IBM has just unveiled a deal with Sony Ericsson. . Both Oracle and IBM also announced deals with mobile phone network vendor Alcatel SA for mobile access to back office applications over mobile data networks including GPRS (General Packet Radio Service) and 3G (Third Generation) networks.
For Oracle, the alliance with Alcatel is about the Mobile Field Services part of its 11i E-Business Suite of applications. IBM worked with Alcatel on making WebSphere and Lotus software accessible on pocket and laptop computers.
