Sorry mate, I'm not going to lie, I didn't even see that sticky until after I'd posted, so I had a feeling somebody would move it. Won't make the mistake again.
Yeah, I would've thought it had to do with the hold switch as well, but thinking about it, it would go to the big red cross logo, opposed to the small black one when it was plugged in, which is part of the apple firmware, so by that point it was already there. I tried a complete reinstall of rockbox, and it's all working fine as far as I can see now. Weird, but thanks for your help.
