Could someone explain to me, I just downloaded the 1.1.3 apple update sotware. This is just the update where you do the check for update option in iTunes, not anything to pay for. Anyway, I did this and it was about 150mb in size and since downloading all I've noticed is a coloured bar on the dock. No other updates, nothing else has changed, just this bar at the bottom. Other than that the icons are in a slightly different place. Otherwise there are no noticeable changes. Is this all that was meant to happen?
