Apple has made the 4th beta of it’s iPhone SDK (Software Developers Kit) available to iPhone developers. The new version of the iPhone SDK has support for OpenGL ES for the iPhone emulator that is included in the SDK. Before the support for that came out, to truly and reliably pop quiz iPhone applications, the developers would have to load the application onto the iPhone.

You can download the new SDK by visiting the iPhone Developer Center. The new SDK weighs in at 1.15GB, so whether you have a slow connection, you should probably get that download started so you can start playing with the new SDK by wee hours.

“The fourth beta version of the iPhone SDK includes Xcode IDE, iPhone simulator with Open GL ES support, Interface Builder, Instruments, frameworks and samples, compilers, and Shark analysis” tool.

Apple plus took the opportunity to drop a new firmware build 5A258f.  It is of course only available to choose developers. It is not known whether the Pwnage Tool, in it’s current scheme, will work. It could take a little while for the Pwnage Tool to catch up with the new firmware. The firmware file is 200MB, much more bandwidth friendly than the SDK.
