Apple has just released their iOS 4.3.2 for iPhone 4/3GS, iPod touch 4G and 3G and iPad 1/2 users. This new OS fixes some issues. This version fixes blank or frozen video during FaceTime calls and 3G issues that prevented international users from connecting to the 3G networks using the iPad Wi-Fi + 3G.
The previous version was released in less than a month, and here comes the new iOS 4.3.2.
To update your device, just connect it to Mac or PC and Check for Updates in iTunes. Your device will be automatically updated. Just note that its size is 660 MB, a hefty one.
