From the mouth of Steve Jobs himself, Apple wants third party native applications on the iPhone and is developing an SDK for Developers, to debut in February, 2008. Steve notes, in a post on Apple’s Hot News site, that the company is both trying to enable an iPhone platform, while at the same time, protect users from potential viruses and malware.
He also notes the tumult in the blogosphere and developer community about not hearing anything to now, asking, “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.”
Applications written for iPhone will also work on the iPod Touch.
