RedSn0w will ask you if this is a newer (fixed) model iPhone. Newer models of the iPhone 3GS have a fixed bootrom which requires you to connect your device to the computer each time you wish to reboot.

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.
