I got an iphone 3gs today. Its nice. basically the exact same as my ipod touch, but with gps and a (crap) camera.
i uploaded all the apps I had for my ipod, synced my calendar, contacts, mail accounts, setup the settings and thought ‘great, what do I do now’. I am into cycling. so im going to use the gps to track the places I cycle (and also to geotag photos I take)
