iOS 4.3 for iPad and iPhone Is Out – Adds Safari Speed-boost, AirPlay Enhancements and More

Share This:


As predicted by yesterday’s revised rumors, iOS 4.3 has been released today and is available for download and install right now in iTunes. As with any iOS update, you just need to plug your iPad into your PC and you should be prompted that there is an update available to apply. If you’re not just click the Update button on the info page for your iPad and then you’ll get prompted.

The big additions that the 4.3 update brings to the iPad are:

Safari Performance Boost: There’s a new ‘Nitro JavaScript Engine’ that is said to run javascript twice as fast as in iOS 4.2 – meaning faster page loads.

AirPlay Enhancements: There’s now support for streaming videos from the Photos app, and support for video out of third party apps was promised for this update, though Apple’s wording on their 4.3 for iPad page is a little vague to say the least:

Even AirPlay-enabled apps and websites get the big-screen treatment with iOS 4.3.

iTunes Home Sharing: You can now play content that resides on your Mac or Windows PC – music, movies, TV shows, audio books etc – on any iPad, iPhone, or iPod Touch on the same WiFi network, without any need to download or sync content to the devices.

The Return of the Rotation Lock: This is the most welcome change of all for many of us. After the 4.2 update stupidly changed the top-right external button on the iPad into a mute switch (and a redundant one at that) rather than a rotation lock as it was originally, we now have the option (within the Settings app) to decide whether the button is a rotation lock or mute switch.

I’ve only just installed the 4.3 update and had a very quick play with loading a few sites in Safari. It seems maybe a little quicker so far, not dramatically so – but it was a very quick look.

How are you finding the 4.3 update so far?
