i wanted to share this because i know a lot of people don't like some of the apple applications (i.e. weather and stocks) and get better ones from the app store. well in 3.0 you can hide those applications you don't use. in 3.0 there are no limit to the number of apps you can install (besides storage space of course). whenever you fill up all of your home screen pages and install a new app, no icon is displayed but the app can still be launched from spotlight. this also happens when the last page is full and you add another icon to it. the last icon on the page will disappear. you can use this to hide apple applications that you don't use. to do this, move 16 icons to the last home screen page (if you don't have that many apps, you can add blank pages in between). make sure the last icon is the one you want to hide. now drag one more icon to this page. the last icon will disappear. you can still get to this app by searching for it in spotlight. you can get the icons back by turning the device off then back on again.
