Unlike most other smartphone platforms, Windows Mobile doesn’t come with a mapping application pre-installed by default. While this may very well change with the soon-to-be-announced Windows Mobile 7, it has thus far been up to the handset manufacturer to throw in a map app if they so choose.

Later this week, messaging/location technology providers TCS will announce that Sony Ericsson has chosen their turn-by-turn application, Gokivo, to be pre-loaded onto future Sony Ericsson-made Windows Mobile devices.

The first Sony Ericsson handset to come with Gokivo out of the box will be the Aspen, which was just announced last week.

This is pretty big news for TCS; they just acquired the company behind Gokivo, Networks In Motion, back in December, and this is the first time any manufacturer has chosen to pre-install the app at the factory.

The flagship features, according to TCS:

• Local Search
• Traffic and Weather
• Location Sharing

While it’s great news for TCS, I have to wonder: with Nokia and Google’s recent moves toward making turn-by-turn navigation a standard feature on S60 and Android, how much longer will smartphone consumers be willing to cough up a subscription fee?
