I recently bought an iPod touch and was pretty happy with it, but the wi-fi failed on it for some reason forcing me to exchange it for a new one. The first thing I noticed about the new model was the "1B" in the serial number, followed by 827xxxxxx. Doesn't this mean it's a week 27? What I don't understand is how this is possible given that it's Aug 30th 08.... I heard that the "B" doesn't matter too much, so I also checked for the "requires 7.4 or higher..." but it reads 7.6 too, and has Lennnon on the box. So what the hell is it? And if it is a week 27 are there any bugs I need to worry about? So far performance has been normal except that the standard iPod hiss (I've never owned one that didn't) is a bit bass-y? Any help would be appreciated.
