Currently, Google is the default search on the popular mobile device, although you can easily go into its settings and switch the search option to Yahoo!. Few consumers do, though. Microsoft has been in talks to be added to search options for a long time, but has wanted to do so in a way that give users of iPhone more choice in a wide range of services. But, whether Apple would make Microsoft's Bing the default or whether it would simply allow iPhone users more of a choice among search services is unclear. While being an option isn't the same as completely replacing Google, it would give Bing a well-known platform to show off its technology to consumers. In addition, Microsoft wants to make its Bing mapping more integrated with iPhone. "Microsoft would like to hip-check Google off of the iPhone, of course. But like rumors that it would pay News Corp. (NWS) to "de-index" its content from Google and display it prominently on Bing, the notion is premature," said Kara Swisher.
