New to the whole 'interested in my mobile' game but I am getting into it after buying a Nokia E51.

So far I have been wowed by the google maps, even made me get a Freedom GPS 2000. Fantastic when I play the Bourne theme tunes and show the in-laws what my phone can do... even had someone go in the garden to wave at the satellite Guaranteed that will become a new party trick, getting people to pretend they can see them.. anyway I digress.

Can anyone suggest anothor gizmo/app that may have equal impact on my easily pleased mind?

Cheers
