Finally! The official Skype client for iPhone has just been updated to include support for iOS 4 multitasking. You can now receive Skype calls and IM in the background while running other apps, and even when you’re in the lockscreen.
Of course, you’re also able to continue your calls after switching to another application, say to check for an email you’ve got while talking.
The app is available for free here.
As for iPad support, please remember that, according to Skype’s Asia-Pacific VP Dan Neary, Skype for iPad was set to come out “this summer”. Maybe the app has been delayed? Summer’s not over yet, but we haven’t had official word about the app since then.
