To find your serial number you can follow these instructions. The week number is usually the 4th and 5th digit of the serial number. For example, a serial number beginning with 88926 would be week 26 of 2009. 3GS units made week 45 or later will usually have a fixed bootroom. Before week 40 they usually have the older bootroom. Between weeks 40 and 45 the results vary.
If you believe your device has a fixed bootrom then press the Yes button. Otherwise press the No button.
