Apple is looking to increase iPhone business by opening it up to third-party developers, with an eye on the business and gaming markets.   In June 2008, users will be able to download the free 2.0 software upgrade, enabling them t

o use third-party software approved by Apple. Included in the free download is Microsoft’s Exchange ActiveSync software, which synchronizes the phone with a PC for email, calendar and contact information. It will also contain the App Store, an application similar to iTunes that will let users browse, search, buy and download programs like games.   With the upgrade, Apple hopes to channel revenue away from Research In Motion’s Blackberry.   Apple says that over 100,000 software developers have downloaded the iPhone software development kit since the announcement last week, pushing the iPhone to the front of the SmartPhone conversation, a place usually occupied by the Blackberry.   The upgrade is aimed at making the phone more compatible for businesses and taking advantage of its features. These include the iPhone’s 3-D processor and “accelerometer,” motion censors that detect when the phone is being tilted.   The iPhone’s technology and a 3.5-inch display screen make it a “blank canvas” to game developers, says Travis Boatman, vice president of Worldwide Studios for EA Mobile. “I can create any kind of interface I want, to make any kind of game experience I want,” he says.   Though only a small amount of cell phone users buy games, Apple is hoping to change that, marketing the iPhone as an all-in-one device. The hope is that the 2.0 software upgrade will make it attractive to the corporate world and those far from it.   By Danny Scuderi   FEEDBACK For comments on this article, email us at
