Hi guys

I'm posting this on behalf of a friend of mine.

She has got a ipod touch, bought brand new 3 months ago but the screen goes white and you can't see anything.

She has been into an Apple store and when they switched it on it bloody worked! so they just said as they can't see the problem there's nothing they can do

Anyway since then it's happened again and again, any ideas?

I have pressed the power button and the middle button when the white screen is on and a Apple sign appears and then comes on BUT it goes white screen again in time.
