While some of the talks dealt with having Yahoo provide more information to Siri, Yahoo also is angling to get the high profile job as official search engine for iOS. That might be considerably tougher to accomplish considering that Apple already has a ten year deal with Microsoft's Bing for the search engine job.
Despite the talks, there is the possibility that no deal emerges between Apple and Yahoo. One source told Bloomberg that Apple routinely meets with other companies to discuss how its products can be incorporated into iOS. Meanwhile, Yahoo is desperately seeking a way to turn around a spark growth in the number of people that visit its sites.
