I received a replacement iPod touch 16gb 1st gen yesterday. Of course, the people over at apple didnt realize the iPod i gave them had 2.1 software on it, and then gave me an ipod with 1.5. I had no problem going to iTunes and downloading 2.2 software, as it realized i already bought it, etc. Once downloaded, i plugged in my iPod, it said extracting software, preparing ipod for restore, restoring ipod. It got halfway through restoring the ipod when a dialog popped up saying unknown error, could not restore the ipod. I went to a different computer (the only other one within the house). Repeated the steps, and itunes did the same thing, unknown error, etc. Now i cannot figure out how 1. how to download 2.2 software over again, where can i find it on the itunes store? and 2. obviously, how to fix this...help please.
