Oh ive figured out folders now, just drag apps ontop of eachother!
Very annoying that when you're on the home screen you can no longer double tap the menu button to get the ipod up. You have no choice but to use the multitasking toolbar :-(
Oh and i found out why multitasking doesn't work, its because the app developers need to actually develop the multitasking feature into the app itself! So could take a while!
