Steve Jobs: Apple Will Open iPhone to 3rd Party Apps in February by Philip Elmer-DeWitt @FortuneMagazine October 17, 2007, 5:06 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Four months after he tried to persuade Apple (AAPL) software developers to use Safari to write their iPhone applications, and after weeks of playing cat and mouse with programmers who risked bricking and wrote native apps anyway, Steve Jobs today changed his tune. In a signed message posted on Apple.com‘s start page, Jobs wrote: Third Party Applications on the iPhone Let me just say it: We want native third party applications on the iPhone, and we plan to have an SDK [software developer’s kit] in developers’ hands in February. We are excited about creating a vibrant third party developer community around the iPhone and enabling hundreds of new applications for our users. With our revolutionary multi-touch interface, powerful hardware and advanced software architecture, we believe we have created the best mobile platform ever for developers. It will take until February to release an SDK because we’re trying to do two diametrically opposed things at once–provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc. This is no easy task. Some claim that viruses and malware are not a problem on mobile phones–this is simply not true. There have been serious viruses on other mobile phones already, including some that silently spread from phone to phone over the cell network. As our phones become more powerful, these malicious programs will become more dangerous. And since the iPhone is the most advanced phone ever, it will be a highly visible target. Some companies are already taking action. Nokia, for example, is not allowing any applications to be loaded onto some of their newest phones unless they have a digital signature that can be traced back to a known developer. While this makes such a phone less than “totally open,” we believe it is a step in the right direction. We are working on an advanced system which will offer developers broad access to natively program the iPhone’s amazing software platform while at the same time protecting users from malicious programs. We think a few months of patience now will be rewarded by many years of great third party applications running on safe and reliable iPhones. Steve P.S.: The SDK will also allow developers to create applications for iPod touch. Jobs’ reversal is a tacit admission on his part that Apple’s programmers can’t do it all. It could also a long way to repairing relations with the software developers the company alienated when its most recent software update wiped out the entire first generation of native iPhone 3rd-party apps.
