A friend's ipodtouch's screen cracked and he is trying to find a way to get it replaced by Bestbuy. The warranty does not cover physical damage, only internal software glitches or failures. I know that I could just load a custom .ipsw and unplug/turn off/mess it up in order to brick it, but will they do an exchange for this? Has anyone tried to do something like this? The itouch works just fine, and if bricking it permanently wouldn't get an exchange then I definitely don't want to be doing it.
