I've got an old 3G Firewire/USB split chord that works perfectly well. I've also got a 3G firewire AC charger. Now, I've been using this for a week with my new ipod 5th gen and I haven't noticed anything bad. I want to know that I can continue using this thing instead of having to fork out $80AUD for a USB charger, which I find is a complete rip-off.
