Astronomy program on Blackberry

[samos]

The popular astronomy program StarryNight can be downloaded directly to a Blackberry for free. Just type in your zip code and it shows the stars in your area ... and it updates itself every minute or so. Really neat ...

However ...you're supposed to be able to pan and zoom in and out ... but I cant figure out how. Has anyone tried this?
Thanks
