ipod touch lost ability to connect to wifi + battery life drains in <2 hours

[gatorgirl1214]

I found some info on this through google, but a search on here hasn't yielded much results.

Ever since updating my software a few weeks ago, my ipod touch loses it's charge after only 2-3 hours, and it also has lost it's ability to connect to wifi (menu says "no wifi" and it's greyed out).

How do I undo this update? I have tried all suggestions I've seen. Doing a full restore to the device, clearing cache, history, and cookies through the menu, and just leaving it dead for a day or two and charging it up again. Nothing is working.

Any suggestions?

have you tried downgrading

I spoke with someone in the Apple store who told me that wasn't possible. I haven't found a way to do so without jailbreaking the ipod.

Is there something I'm missing?
