Man, running Research In Motion (Nasdaq: RIMM) must be one of the hardest jobs in the business world today. Only days after Apple (Nasdaq: AAPL) unveiled its plans for enterprise mobility dominance, Nokia (NYSE: NOK) presents the E90 Communicator, which hooks into tons of business-class Oracle (Nasdaq: ORCL) applications. It's a serious expansion of Nokia's interoperability with Oracle platforms.

The E90 and its antecedents will connect to corporate databases through the Oracle Database Lite framework, with two separate applications for accessing Siebel-based customer management data. An Oracle spokesperson says that the collaboration has been five years in the making, so Finland's finest has seen a need for tighter business integration for quite some time. For Siebel, that timeframe goes back beyond Oracle's acquisition of the business-intelligence specialist in 2006.

The database giant isn't picking sides entirely, though. RIM also got some Siebel love yesterday. It's the equivalent of only one of Nokia's three new business-minded toys, though it's available for eight different BlackBerry models today. Though RIM enjoys wider immediate availability of the Oracle injection, methinks that Nokia is getting the better end of the deal by landing a wider selection of software. And the company can always design a few new phones, or backport the new tools to existing models.

Of course, there has been no announcement of Oracle/Siebel software for Google (Nasdaq: GOOG) Android phones, though that's understandable, since there really aren't any of those on the market yet. Apple's business update hasn't actually happened yet, either, so there's another absentee for you. Other notable absences include the consumer-minded Motorola (NYSE: MOT) and Palm (Nasdaq: PALM).

So the world's biggest, baddest cell-phone maker goes after a new sub-market. I expect the Finns to do well with this so-far unique offering when selling to businesses operating off Siebel and Oracle platforms. And despite some ameliorating trinkets thrown to RIM, it's obvious that the Canadian bacon is getting cooked, one slice at a time. This high-growth gravy train will derail, and soon.
