Following news that iOS 4.3 beta 1 has been seeded to developers, Apple’s servers are no doubt being hammered by anxious developers looking to explore all the new features. We pinged a few of our dev friends for feedback on new additions they’ve found and here’s what we have so far:

  • Personal hotspot capabilities for GSM devices — as we exclusively reported earlier today
  • AirPlay support for third-party native apps and third-party Web apps
  • Redesigned FaceTime icon
  • Multi-touch gesture support 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.”
  • Configurable slide switch for iPad — users can now decide whether the hardware switch above the volume rocker on the iPad controls mute or rotation lock
  • iAd full screen banners on the iPad — bigger ads… just what iPad users have been clamoring for

Interestingly, iOS 4.3 appears to also have dropped support for Apple second-generation iPhone — the iPhone 3G — and its second-generation iPod touch. This could make the current build Apple’s final software release for these devices.

UPDATE: Several readers have emailed us to point out that enthusiast blog iSpazio may have uncovered a little gem. References to the following effects have been found in the iOS 4.3 code, and they might be introduced as live video effects for video capture and FaceTime calls:

  • Thermal Camera
  • X-ray
  • Kaleidoscope
  • Normal
  • Tunnel of Light
  • Collapse
  • Turbine
  • Enlarge
