I've used it once.. With myself. When I tested out the mac app. Although I'm getting my parents a ipod touch for xmas. So It'll get a lot of usage after that so they can see the kids and all. Will also help when they need me to fix stuff and we're in different states. Other than that though I have no use for it. For whatever reason 99% of my contacts that use iPhones went from 3G to 3GS when it came out, but I'm one of the few that went to iP4.
