Six Apart has introduced an iPhone version of their BlogIt software, which allows users to quickly post updates to their blogs, Twitter, Pownce, FriendFeed, Jaiku, and Facebook. The current version of BlogIt is a traditional iPhone web-based app, though we can expect a native version on the way (Six Apart announced a native version of TypePad at Apple’s WWDC conference earlier this week). You can reach the app by pointing your iPhone’s browser to http://blogit.typepad.com/.

The company originally released BlogIt as a Facebook app in April. Both versions currently support posting to Movable Type, TypePad, Vox, LiveJournal, Blogger and WordPress, along with the social networks mentioned above.

The app works well enough, but the release so soon before the release of Apple’s App Store is curious – it will be outdated in a month.
