iPhone OS 4 Beta and SDK has been officially released to developers today via the iPhone Dev Center, as per usual. The first release of the iPhone OS 4 was released earlier in the month after we got our first look at the features of the upcoming OS update. With the new beta you will also have access to firmware for each compatible device including iPhone 3GS, iPhone 3G, and iPod Touch (2nd and 3rd generation).
This new beta release will only be available to developers, iPhone and iPod Touch users will have to wait until some time “this summer” to get their hands on the public release of the OS update. iPad users, on the other hand, will have to wait until sometime “in the fall”.
