I just jailbroke my 1G iPod touch running 3.1.3 with the 3.1.2 loophole. I used to have it jailbroken, but I left it stock for a while. Now I wanted to change the keyboard theme with Winterboard from Cydia, but it refuses to change. I've used MacBook Air Keyboard, 3G Storm Keyboard, iAcces Mac Book Air, but none have changed it. And no, I never had more than one keyboard theme chosen at once and I hit the Respring button on the top left every time I change the theme. Thanks!
