Built a couple of the report samples out to an iPhone emulator yesterday. Even out-of-box the viewer looks pretty decent. The Cognos Viewer navigation buttons are manageable but would be obviously better if specifically designed for the iPhone.
Oracle and MicroStrategy BI both have offerings now for the iPhone so I'm sure we can expect it is only a matter of time until IBM Cognos picks this up.
