What's your battery life on your 3GS like and what week was it manufactured? Mine goes down about 10% per hour with brightness at 25%, push off, notifcations off, Bluetooth off, Nike+ off, fetch off (set to manual), and either 3G or wifi on. Mine has crappy battery life and was manufactured on the 23 week. The 4th and 5th serial number are the week your phone was manufatured. On a side note do you think I would qualify for a replacement?
