Danger's Sidekick 3 has been released for the T-Mobile network.  While
Sidekick aficionados have probably learned all they need from Engadget or Gizmodo, Danger and T-Mobile are cross-promoting this Sidekick site.
It makes good use of a cartoon-style rotating landscape to highlight
product features, with a little entertainment and random discovery thrown in.
