But from a practical standpoint, whether Apple is rooting for Bing to succeed or not, and regardless whether Apple has any actual intention of perhaps switching to Bing as the default search provider for MobileSafari and Safari, Apple almost has to discuss such a potential deal with Microsoft. Even if what Apple ultimately wants is to stick with Google as their default search provider, how can Apple negotiate the best possible terms from Google if they don’t have any other option? (It strikes me as very likely that even if Google remains the default search engine for iPhone OS, Bing will replace Yahoo as the second choice, which you can toggle in the Settings app.)
