Yup, it’s true, the long awaited iPhone SDK is now available. While we wish we were physically there to witness the announcement first hand, we give props to Gizmodo for their coverage of the event. Unfortunately, while the SDK is free, once you decide to make your newly developed application available to others, there is a $ 99 charge for it to be published in iTunes which is the sole distribution mechanism for it.  According to their website, the developer program is intially available in the US with a limited number of slots and will expand internationally in the coming months. Yeah, it’s a real bummer for programmers, but I bet in some part of the universe, some ingenious mind is already working on a way to counter Apple in their grand master plan.

Others notable announcements include support for VoIP over Wifi  and the inclusion of enterprise features such as push e-mail, push contacts and calendar, WPA2/802.1x, security policies, Microsoft Activesync and Exchange support and all the other stuff corporate geeks been dreaming of. Non-developers who want these new features will have to wait until June 2008 for it to become available in the iPhone 2.0 update. New games such as Spore from EA, and Super Monkey Ball from Sega both of which will make use of iPhone’s accelerometer as controls are also in the works as a result of the SDK release.

With these developments adding a little more value and functionality to the iPhone, will hesitant buyers now jump the gun and get one or are they still waiting for more before finally taking the plunge?
