I just thought I'd pass on an easter egg I found in IOS 6 last night.
First, go in to the clock app to the timer tab.
Next, set the timer ticking down and start it.
Finally, double tap with 2 fingers. You will hear a double defending tone. Double tap with 2 fingers again, and you will here an ascending tone. What is happening is you are pausing and unpausing the timer.
Really cool stuff I think.
IOS 6 may be lacking some real big features, but it seems to be making up with little random nice things here and there.
Hope you find this of use.
