It says to unlock bambo blade you have to play in zen mode for 5 days in a row. You don't want wait 5 days so first play zen mode than when you are done playing it go to you ipod/iphone settings. Next find general and when you go to general find date and time. And last turn off the automatic time and date and find where it says set date and time and then just change it to next day. Example: april 21 and change it to the 22nd. When you change it to the next day play in zen mode again, when done with zen mode change the date to the other next day until you did it 5 times. Doing this trick will take about six minutes.
