TechCrunch is citing a “reliable source” who claims that Bing will be getting the nod as iPhone OS 4′s default search engine once the finalized code is pushed out to the masses. Search rival Google has been the default iPhone search provider since its inception in 2006; an honor for which Google allegedly pays close to $100 million a year. Mobile search is becoming huge business and as the Android platform juggernaut continues to chug along — with Google search in tow — alternate search providers like Microsoft and Yahoo! are looking for mobile delivery vehicles. What do you think iPhone owners? Loyal to Google or will you give Bing a shot?
