Apple has launched iOS updates for its various devices. The main update is iOS 4.3.2, designed to fix bugs with the original 4.3 software.

Among the bugs the update addresses are FaceTime display and WiFi +3G connectivity issues.

The 4.3.2 update is available for the iPhone 3GS, AT&T iPhone 4, iPad, iPad 2, and iPod Touch 3rd and fourth generations.

There is also an iOS 4.2.7 update for the Verizon iPhone. This one comes with bug fixes and security updates.

Users can download the updates through iTunes. MacStories has direct links to updates for each device.

iOS 4.3 was launched in March. “With more than 160 million iOS devices worldwide, including over 100 million iPhones, the growth of the iOS platform has been unprecedented,” said Apple CEO Steve Jobs upon its announcement. “iOS 4.3 adds even more features to the world’s most advanced mobile operating system, across three blockbuster devices—iPad, iPhone and iPod touch—providing an ecosystem that offers customers an incredibly rich experience and developers unlimited opportunities.”

New features of iOS 4.3 included faster Safari mobile browsing performance with the Nitro JavaScript engine, iTunes Home Sharing, enhancements to AirPlay, the choice of using the iPad side switch to either lock the screen rotation or mute the audio, and a Personal Hotspot feature for sharing an iPhone 4 data connection over Wi-Fi.

A real iOS upgrade is expected in June at Apple’s Worldwide Developer Conference, which was announced last month.
