Apple has released the fourth beta version of iPhone OS 4 and the associated software development kit. The release is not much of a surprise given that Apple has taken to biweekly releases of its iPhone development tools and today marks two weeks since the release of the third beta version.
The new beta update provides firmware for each of the supported devices (namely the iPhone 3GS, the iPhone 3G, and the 2nd and 3rd generation iPod touch).
If Apple’s development cycle for iPhone OS 4 is staying true to major releases that came before it, we should be quickly approaching the final build. We’ll see OS 4 ship out to everyone within the next month or so.
You’ll need to visit the developer site and check out the specifications for yourself. Apple will be releasing 4.0 into the general iPhone population this summer. An iPad version will debut in the fall.
Apple’s servers get slammed whenever a new SDK is released. You may want to wait a few hours if you encounter any problems connecting to the developer site.
