Mimoco has announced a joint project with Infectious to bring their Mimobot character to your iPhone. Currently, there are two iPhone Skins available - Fairybit (left) and MIMOscape (right). Each skin runs $14.99 and can be reapplied over and over again.
I have one of these for my iPod Touch, and it's well worth it. Infectious has gotten a hold of some great artists, so one of your favorite toy designers is probably represented.
