iOS devs, time to get to downloading, as Apple has just released iOS 4.3 beta 2 alongside the iOS SDK 4.3. Downloads are available for the iPhone, iPad, iPod touch, and even the 2nd generation Apple TV. The SDK build is 10M2508a, while the software for the devices is build 8F5153d. From the looks of things, this beta is all about checking and testing AirPlay video with the iOS devices and Apple TV. We will keep our eye out for any other new hotness in this build.
