After announcing its existence during the iPad 2 event last week, Apple has made it available for all. The iOS 4.3 update offers (most importantly) the mobile hotspot feature for AT&T iPhone 4 users and AirPlay support for third-party apps along with various enhancements/ bug fixes. This update is available for the iPhone 4/3GS, iPad, Apple TV, and the last two generations of the iPod Touch. Just plug your iDevice to your iTunes to get started. All of you i4 users on AT&T enjoy your hotspots.
