Skype’s iPhone application has received a much-anticipated update , bringing support for multitasking in iOS 4.

- Run Skype in the background with multitasking in iOS4. Receive Skype calls and IM while other apps are running or when your iPhone is locked. You can also continue your call while you switch to another application. Multitasking is available only with iPhone 4 and iPhone 3GS.

In a blog post on the release, Skype also announced that it has dropped plans to charge for calls made over 3G networks. The company had previously stated that it was planning to institute charges after an introductory period of free calling.
