I read in the Daily Mirror today that application software [apps] for iPhone or Blackberry etc includes StarMap that identifies what constellation you're pointing your phone at in the sky - could be a boon for WAB astronomers - cost £6.99
phone extra
Other apps include europe SatNav [via GPS signal], spirit-level [and realistic beerglass drained as tilted] - these apps are combined, I suspect, in SkyMap - clever really.
