Live Search mobile has relaunched as Bing Mobile at m.bing.com. It's just a rebranding in this case because none of the new functionality from the Bing interface makes it into the mobile version (screenshot below).

1-800-Call-411 has also been rebranded "Bing 411." This is a different number than Call-411, but both numbers send you to the Tellme-driven service now announced as "Bing 411." This is a much richer and more complete experience than Goog-411 (this is a case where it's clearly better not just a little better). In addition to business listings you can get movie times, traffic and weather. And they've put back search by neighborhood, which is an incredibly valuable feature. Dan Miller's observations on Bing 411 are posted on the Opus Research site here.

When you search for restaurants on Bing 411, for example, it also offers you a star rating as opposed to just the business listing information. This is consistent with Microsoft's presentation of Bing as a "decision engine" rather than just a search engine.

If Microsoft were really smart it would do separate marketing around Bing 411 to get mobile users engaged with it. That would in turn drive branding, adoption and loyalty (to varying degrees) on the PC search side.
