An today announced: “As Apple prepares to announce its iPhone SDK, Marketcircle’s CEO Alykhan Jetha (AJ) believes that the SDK’s Cocoa/OS X based mobile platform and the iPhone’s presence in almost every country on earth offer exponential upside for both Apple’s products and the products of independent software developers that can exploit the SDK. Anticipating that the iPhone would be a significant device to grow Apple’s market share, Marketcircle’s flagship productivity management software product, Daylite, started using Apple’s Sync Services last September so Daylite users could share calendar and contact information on iPhone.
