Apple's iOS 4.3 a welcome update for iPad, iPhone

A faster Safari, enhanced AirPlay, and security fixes make it a must-have

With iOS 4.3, Apple is introducing a few device-specific features that users wanted. For instance, iPad owners can now use the switch located on iPad's side either as a mute button or to lock the screen rotation. Apple changed that button's function in the last update, annoying iPad users who'd grown accustomed to locking the screen rotation with it.

AppleTV, which has increasingly become part of the digital home/iOS ecosystem, gains some nice additions too. Netflix subscribers will be thankful that AppleTV can finally stream movies in 5.1 surround sound (if the movie supports it); and sports fans will love the ability to access NBA and Major League Baseball content on their AppleTV (after purchasing subscriptions to NBA League Pass and MLB.tv, respectively). Even without a subscription, the new channels offer live scores, standings, game match-up previews (in high definition), and even highlights in high-definition. This is huge. Now I can be my own ESPN.

Personal Hotspot
For AT&T iPhone and iPad users, iOS 4.3 delivers a new personal hot spot option that allows you to share your cellular connection with up to five other devices.

The Apple TV update extends AirPlay compatibility with third-party apps, delivers a slightly new keyboard interface and features updated slide show themes.

Personal hot spots

It's now possible to set up personal hot spots with iPhones and iPads through AT&T. This feature has been available on Android devices for a while, and it's been on my own "Features I Want in iPhone" list for years. Put simply, iPhone users can now share their 3G data connections with up to five devices. This update, which arrives a month after the iPhone for Verizon hit store shelves, allows three devices to share an Internet connection via Wi-Fi and another two to go online via bluetooth or USB connections.

To use the personal hot spot feature, you'll need to buy additional data services from your cellular provider, so while iOS 4.3 supports this, you have to pay more to play. AT&T charges $45 a month for a bundle that essentially lets you use 4GB of data per month -- and it charges you $10 per gigabyte if you exceed that limit. Personal hot spot capability is a long-awaited update, but it could get costly if you use it a lot.

How does iOS4.3 run?

This version of iOS 4 is stable; I haven't had any problems with apps crashing, and the update itself went smoothly. AirPlay functionality is noticeably more reliable. This is important because, with the last update, there were times where I wanted to stream music to AppleTV but the AirPlay icon was missing, even though everything was set up properly. I didn't have any such problems during the months-long beta testing of iOS 4.3.

There are a couple of annoyances, though. First, the Camera app takes longer than it should to load. When iPhone 4 was released, the app launched instantly. With each update, that launch-time lag has grown. I've missed snapping some great photos because I was waiting for Camera to load.

Another annoyance: you can share photos or videos through Airplay in Photos now, but you still can't beam photos or videos through using the Camera Roll, which is where photos are stored within the Camera application. This seems like an un-Apple-like oversight. For instance, you can't take a picture or record a video and then beam it via Apple TV to your HDTV. Instead, once you record the video or image, you have to press the Home button, go to the Photos app, tap the appropriate album -- in Camera Roll, by the way -- navigate to the photo or video, tap the AirPlay icon, tap your destination and, if you're beaming video, press play. This isn't a deal-breaker, obviously, but adding AirPlay integration to the Camera app really couldn't have been that hard.

Still, it's better than iOS 4.2, where you couldn't stream recorded videos or photos from your Photo Camera Roll at all.

As it stands, iOS 4.3 delivers needed security updates and several features that iOS device owners will like. Of course, speculation is already swirling about iOS 5, but this update should keep most users happy until that version appears. Version 4.3 may not clear the entire list of must-have iOS features, but it sure is better than the alternative.
