Cognos Mobile has been around for about five years under the name Go! Mobile. Go! Mobile supported Windows smartphones first and then eventually also supported Symbian and BlackBerry phones. This was accomplished through an application that was installed on the device and also a server component on the Cognos BI serve.
The reports that came to the phone would automatically scale for ease of use and interaction on the phone, but were far from being interactive due to the lack of a touch interface, which we see in modern phones today.
