If you're hankering to be riding the very latest mobile software from Apple, hit up your iTunes, for version 4.3.2 of iOS is now available for downloadin' and updatin'. Fixes for occasional "blank or frozen" FaceTime video and iPad 3G issues get top billing, while the obligatory security updates fill out the rest. The size of this mighty software drop? A hefty 666.2MB.
Update: Well, someone's skipping class today. A tethered jailbreak is already in the wilds, if you dare. Thanks, Jeff!
Update 2: Looks like Verizon customers are getting a slightly different update of their own: iOS 4.2.7. It promises only "bug fixes and security updates."
