Apple has recently announced the beta release of the 5th version of the iPhone SDK, which contains the framework, tools and compilers for making your own custom applications for Apple’s iPhone operating system. It provides also provides a simulator to run your apps on, which represents both the iPhone and the iPod touch. There doesn’t appear to be a lot of changes to this kit other than bringing it up to the latest OS version, but the download is free and there’s no sense working with the older version.

iPhone Developers

Within just 4 days of Apple releasing a beta version of the software development kit (SDK) for the iPhone, the company claims they’ve already had an incredibly positive response with over 100,000 downloads. This is good news for iPhone owners since there will likely be more useful and fun applications available for the iPhone soon from third party developers.

Multiple development shops have already announced plans to offer applications for the iPhone with Gameloft being one of the most hyped with 15 games planned for the iPhone yet this year. Unfortunately, even though the SDK is out and Gameloft can get these games ready quickly, they won’t be available for download until the App Store opens in June.

Apple sent out invitations to reports this week for press announcement concerning the details of the iPhone SDK. Jobs said it would happen in February and the date is set for next week on March 6 which we’ll call close enough. The expected information will allow developers to create third party applications that will run on the iPhone and the iPod touch, ridding the need for the hack and fix battle that Apple has been dealing with this past year.
