If you like the idea of easy entry mobi domains there are plenty four letter
ones not yet registered. Any combination of letters adgjmptw without any
immediate repeats is an easy entry mobi domain name. e.g. pamd.mobi is still
available. If the keys are together on the pad, so much the better. For
mobiles which have the .mobi domain as default it will be possible to enter
these domain names much more easily than any others.

gpg.mobi is currently under auction at sedo.com.
