The new beta of iOS 4.3 carries build number 9F5135d and is available for all three of Apple's iOS devices -- the iPhone, iPad, and iPod touch. Thus far, it's too early to tell what changes may come baked into the release when compared to the first beta, released exactly one week ago.
The first beta of iOS 4.3 introduced a personal hotspot control panel, new multitouch gestures for the iPad, and updated SMS alert settings. Resource files accompanying the release also provided hints at a handful of new iPad and iPhone models, as well as a potential "Find My Friends" social networking feature.
It should be noted, however, that the multi-touch gestures that made their debut in the first beta won't be ready for prime time by the final release of iOS 4.3, according to a note to developers accompanying the release of the second beta.
"This feature will not be enabled in iOS 4.3 for customers," the documentation reads, "but we are providing this preview to gather input on how these gestures work with your apps."
