I have read through a couple of these threads but they all seem to have been rendered obsolete by the changes to the bootloader (this spring/winter I think?) Also, mikeage.net seems to have been a resource but all bootloading related stuff has been pulled from his web site.
To clarify: Instead of having to use the 'lock switch' to load apple firmware instead of rockbox, I want to reverse the procedure and have my nano load the apple firmware by default (and only load rockbox if the lock switch is used). It's a holiday thing: power conservation is top priority and it's not exactly rockbox's forte

Can anybody help with download locations, instructions or?
