Apple today announced the availability of iOS 4.3 Beta for iOS devices. The new update brings enhancements to AirPlay streaming, specifically streaming to Apple TV’s from within Apps. It also brings full screen iAd banners and an update specific to the iPad that includes multi-touch gestures. There seems to be no mention of supporting a hotspot similar to Verizon’s iPhone which will run iOS 4.25. Only time will tell.
Update – iOS 4.3 for the iPhone does have mobile hotspot support.
Here’s a list of enhancements:
Enhancements to AirPlay – Stream video from your app to a widescreen TV using new Media Player APIs that support AirPlay video. You can also update your web content to support AirPlay.
HTTP Live Streaming Statistics – Track the popularity of your streams and measure their performance. New AVFoundation APIs allow you to track information including how many people are watching your videos, how long they’re watching them, and performance metrics like observed bitrate and number of dropped frames. Use these statistics to fine tune your authoring process and deliver optimized content to your users.
iAd Full Screen Banners – iAd full screen banners grab the attention of users by taking advantage of the large screen of iPad to launch an immersive, interactive iAd experience. This new banner format is easy to implement. And Apple sells and serves the ads to your app while you collect 60% of the advertising revenue generated.
Multi-Touch Gestures for iPad – This beta release contains a preview of new Multi-Touch gestures for iPad. You can use four or five fingers to pinch to the Home Screen; swipe up to reveal the multitasking bar; and swipe left or right between apps. We are providing this preview before releasing them to the public to understand how these gestures work with your apps.
