I finally tired of having to turn wireless off over and over again, so I looked up reverting to 3.1.2. You lose all of your settings, but for me it was worth it since the ipod is more responsive now (I could sometimes count 3 seconds just to bring up the music player) and now battery life doesn't vacuum.

Mine is a iPod Touch 32GB 2nd Gen.
1. Download software: http://www.felixbruns.de/iPod/firmware/
2. In iTunes, Option/Shift click the Restore button
3. Aim at your downloaded firmware
4. Restore
5. Rejoice

I'm surprised it's taking them this long to fix it. Perhaps they diverted all resources towards the iPhone "non"-issues ;-D
