At last, Google is permitting the Nexus One to use multi-touch for maps, photo galleries and the Web, however, of little consolation to owners of Motorola's Droid and T-Mobile's G1.

Rumors have revealed that Apple had requested that Google to avoid multi-touch back when the companies were cozy, but Google may no longer seek to comply now that the relationship has soured.
