PCWorld: What’s New In iOS 4.3 Mobile Operating System?
At the same time as it introduced its new tablet, iPad 2, Apple upgraded the iOS mobile operating system, adding a useful instant wireless hotspot feature among other improvements.
“You might describe iOS 4 as a long-term investment. While the initial version brought us the much-demanded multitasking, subsequent updates haven’t been restricted to mere bug fixes. Instead, we’ve gotten a slew of noticeable, if not major, improvements: AirPlay, AirPrint, Game Center, and so on. The newly released iOS 4.3 is no exception, bringing not only a couple of significant enhancements in the form of the Personal Hotspot feature and Home Sharing, but also some smaller niceties as well.
As with iOS 4.0, the 4.3 update plays well with only certain models–and on top of iOS 4.0’s limitations, 4.3 narrows the field even further. You’ll need an iPhone 4 (the GSM version only–sorry, Verizon iPhone owners) or iPhone 3GS, an iPad or iPad 2, or a third- or fourth-generation iPod touch to take advantage of the update.”
