iOS 4.2.1 and iOS 4.3.2 are two different versions of Apple’s mobile operating system for the iPhone, iPad, and iPod Touch. They have many of the same features, but there are some key differences between them that you should know about before deciding which to install on your device. In this blog post, we’ll take a closer look at these differences and help you decide which version is right for you.
What is iOS 4.2.1?
iOS 4.2.1 is the most recent update to Apple’s iOS operating system. iOS 4.2.1 is a free update that is compatible with all iPhone, iPad, and iPod touch models running iOS 4.0 or later. iOS 4.2.1 includes bug fixes and improvements, such as improved Bluetooth support, better battery life for the iPhone 3G, and the ability to sync Exchange contacts on the iPhone 4. In addition, iOS 4.2.1 introduces AirPrint, a new feature that allows users to wirelessly print photos, documents, and web pages from their iOS devices. iOS 4.2.1 is available now as a free update from Apple’s App Store.
What is iOS 4.3.2?
The iOS 4.3.2 software update contains fixes for bugs that could allow an unauthorized person to gain access to certain parts of the device, as well as other stability improvements. iOS 4.3.2 is available for iPhone 4 (GSM model), iPhone 3GS, iPod touch (4th generation), and iPad 2.
Difference between iOS 4.2.1 and iOS 4.3.2
iOS 4.2.1 was released on November 22, 2010, and iOS 4.3.2 was released on March 25, 2011. iOS 4.2.1 added support for the new multitasking features introduced in iOS 4. iOS 4.3.2 added support for the iPad 2 and the Verizon iPhone 4. It also included fixes for security vulnerabilities and bugs that had been discovered since the release of iOS 4.3.1. iOS 4.3.2 is the last version of iOS that is compatible with the original iPhone and iPhone 3G. iOS 4.2.1 is also the last version of iOS that is compatible with the second-generation iPod touch and fourth-generation iPod touch.
Although there are some minor differences between iOS 4.2.1 and iOS 4.3.2, the changes are not significant enough to warrant an upgrade for most users. If you have an iPhone or iPad that is currently running iOS 4.2.1, we recommend waiting until Apple releases a more substantial update before upgrading your device’s software. However, if you are experiencing problems with your current version of iOS or if you need to take advantage of one of the new features in iOS 4.3.2 (such as AirPlay mirroring), then upgrading to the latest version is definitely recommended.
