The company, which has joint HQs in Tokyo and Stockholm, has been a licensee of the BlackBerry technology from Canada’s Research In Motion Ltd for over a year as part of the BlackBerry Connect program, which extends the functionality of the service from RIM’s own handsets to third-party devices.

The Exchange push capability is new and derives from the development of ActiveSync support within the RoadSync product from DataViz, which underscores the ability to push Exchange data to Symbian, a non-Microsoft operating system. For this reason, Sony Ericsson has also become an ActiveSync licensee, a status already held by DataViz and Nokia, the other handset manufacturer with a device to which RoadSync can push Exchange data.

In a parallel announcement, Sony Ericsson said it was delaying commercial availability of the P990, which is a high-end device with imaging and entertainment functions, until the second quarter, blaming difficulties in setting up manufacturing relationships and ramping up output.
