About 2 months ago, I had bought an AV cable from Ebay (this is not the one sold by Apple and cost me $15 against $50 by Apple). The firmware I was using was 1.1.5. It was working good for these 2 months and I was able to view my movies on my television set. Last night, I did an update to my ipod Touch with firmware 2.2 and now, I realize that my AV cable no longer works. Is there a way for me to revert my update or at least be able to utilize my AV cable? I hate spending $50 to buy an AV cable. Please suggest.
