i'm looking for device to entertain me. as long as it has apps, i'm hooked. i only care about space as long as it fits in a large backpack (and both of them do, so no worries for me) i would prefer iphone 4 but it's easier to loose and i admit, that's definitely going to happen in 3 years. which one is cheaper in australia. i don't care about GB or seriously techno stuff. please help!
