Android phones seem to have social networking pretty sewn up. There are various launcher widgets providing a 'friend-stream' which aggregate Facebook, Twitter etc.

The Tweetdeck app also allows Facebook and Twitter in a single stream.

The Tweetdeck app on the iPhone doesn't seem to allow this - only allowing you to look at feeds on separate pages. Is there anything (either free or paid for) on the iPhone that presents FB and Twitter as well in a single stream as Tweetdeck on Android?

Vodafone have an app on iTunes for this, anyone can use it I think

I can't find this, do you know what it is called?
