Rearden Commerce, the Silicon Valley company that offers a digital concierge service online, has launched its mobile version.

I first talked about the Rearden’s mobile service, called a “Mobile Personal Assistant” earlier this month. It offers ways to keep travel itineraries, track weather, manage your calendar and more. It gives you status updates and alerts around these items, and features a carousel that lets you reel through the items easily (see arrow in image, which points to the carousel on left hand side).

It’s not clear how popular the Foster City, Calif. company’s service will be. At the outset, it’s aiming for the high-end professional, with a Blackberry version.

It’s also not the most open service, showing you only Zagat restaurant reviews, for example, but not Yelp — though the company says it may change that in the future.

One thing is for sure; the company is serious. It has raised $100M from investors to push this service.
