Six Apart is a fave around these parts — They power Vox, TypePad, and our current platform for Phone different, Movable type. They’ve already developed an iPhone-friendly interface at http://i.typepad.com/ for TypePad and now it looks like they’re intending on making it native. See:

Developments for native iPhone support are underway and will comply with the guidelines set by the iPhone Software Developer’s Kit. – [TypePad Mobile]

You could also check out the Press Release if that’s your thing. Our hope: don’t keep this thing limited to TypePad, ok? We like Vox better anyhow. (Off topic: It’s also a pity you guys couldn’t integrate LiveJournal, but ya gotta do what ya gotta do)
