Earlier this afternoon, Apple pushed out the iPhone SDK 4.0 Beta 2 and the iPhone 4.0 Firmware Beta 2 (8A248C). This comes just under two weeks since the original release of iPhone 4.0 Beta 1 on April 8, 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
  

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.
