Apple today released iOS 4.3.2 that includes bug fixes and security updates. The update applies to the GSM iPhone 4, iPhone 3GS, iPad 1 and iPad 2, and the 3rd and 4th-generation iPod touches. The bug fixes are said to include a fix for a bug that caused video to go blank or become frozen during FaceTime calls and another bug that kept some international iPad users with 3G models from connecting to local cellular networks. iOS 4.3.2 does not apply to the Verizon iPhone 4, which has its own update available today as well. iOS 4.2.7 for the CDMA iPhone 4 includes bug fixes and security updates.
