Good news! Skype have just updated their iPhone app to take full advantage of iOS 4, bring the much sought-after functionality of backgrounding the app. That’s right – you can now have Skype permanently running in the background on your iPhone! Ok, so I’m the only one who’s genuinely excited about that, but it is a handy feature, and is not noticeably detrimental to battery life (on which I keep a keen eye, so I’d have noticed!).

Skype will also let you receive calls while the phone is locked. If you hadn’t downloaded the Skype App for your iPhone yet, you should know that the app allows you to make calls over WiFi and 3G, and of course instant message over either, as well. One last thing to note, folks – as backgrounding an app obviously requires multitasking, this will only be supported on the iPhone 3g(s) and iPhone 4.
