Keep Wifi active even if locked?
Just wondering if there is a way to easily keep my iPod Touch active and on Wifi even if I lock it? Basically I'm just wanting to blacken out the screen to save on the screen (much like a screen saver). Battery life isn't an issue, I would just like it to continually sync up via Fetch while saving on the screen.
Any suggestions or advice are appreciated. Thanks!
