Don't you think iPhones should have a startup sound? I've always loved macintosh computer startups, because apple makes them cool, they should really make iPhone/iPad startup sounds. 🙂
On me old Razr, not only it let you assign start and shutdown sounds but full animation video, but I never assigned it a startup anything, like when I turn it on I am in a hurry and don't need any more delays. Shutdown though I had that Terminator sequence where it goes down the furnace and the visor/screen shuts down. 🙂
That statement right there is an open indictment on Apple's view on silencing your iPhone. You should not HAVE to turn it off to make it perfectly silent!
Do Not Disturb (at least under iOS 6) only works when the phone is unlocked. Ring/Silent switch? Hey that works, except if you forget to turn off an alarm!
When I had my Window Mobile 6.1 Pro phone I could silence the entire thing by pressing and holding one button. Apple takes two or more toggles and if you want to be safe you got to turn it off completely.
