Skype has always sort of served as one of the poster children for why iOS just had to allow applications to run in the background. I mean, come on: being able to avoid gobbling up my precious minutes without having to keep the application open all the time just so I don’t miss calls? Yes. Yes please.

Its been a few weeks since iOS launched to the multitasking masses — and today, the dream of always-on Skype becomes a reality. Skype just pushed an update to their application which adds support for iOS 4′s multitasking abilities. Incoming call while the app isn’t in view? You’ll see a prompt, like the one above. Need to pop into another application while on a call? No problem — the Skype call will continue, just as a traditional carrier call would. Go Go Gadget App-Store-link!

Update: Even more good news! Remember how Skype was planning to start charging for Skype-to-Skype calls made over 3G? Yeah, they dropped that idea. You’ll still have to pay for SkypeOut if you’re making Skype-to-not-Skype calls, of course — but if you’re just calling another Skype user, you’re in the clear regardless of what network you’re on.
