iPhone Firmware 4.0 Beta 4 Now Available To Developers

This evening, Apple pushed out the iPhone SDK 4.0 Beta 4 and the iPhone 4.0 Firmware Beta 4 (8A274B). This comes exactly two weeks since the last release of iPhone 4.0 Beta 3 on May 4, 2010.

Apple typically follows a 2-week release schedule for beta releases of iPhone firmware.

The firmware 4.0 update is to deliver a slew of new enhancements, some of which are detailed below:

  • Multitasking
  • Custom homescreen backgrounds
  • Camera 5x Digital Zoom
  • Application Folders
  • Places and Faces in the Photo App
  • Bluetooth Keyboard Support
  • Screen Orientation Lock

Also remember, if you have your iPhone/iPod Touch jailbroken or unlocked, you should not update to 4.0 when it is released, as you will lose both your jailbreak and unlock.
