Since iTunes 7 I have not had any success updating software on my iPods. I have a nano and a mini (both earlier generation). When trying to update software using iTunes 7 (rather than the old iPod Updater) I get an error about my firmware file being corrupt. I have tried the solution on the Apple site for this (delete update files in library/itunes/ipod updater and then try again) but it just redownloads the file and gives the same error.
Anybody else run into this?
