I remember Jobs saying something to the tune of "If you need to have any control over multitasking, then the phone is not doing it properly." As such, I indeed don't know if/when my phone is multitasking, nor have I seen any difference in battery/performance/app start-up speed since downloading iOS4. What I have noticed, however, is that I've lost the shortcut to my Favourites and iPod now that double-clicking the home button brings up the multitasking. And I'm really missing them. Can I turn off multitasking or reinstate what double-clicking does? After all, Steve Jobs himself said that I should never need to know my iPhone is multitasking, so why tie-up such a useful shortcut?
