Interesting...I hit Check for Update, and its showed the 3.0 update available. There was an option to download and install. I clicked it. It started downloading. I didn't get charged. (I have an iPod Touch 2G). I immediately though..."thats not right". I don't know if it will ask me to pay later down the road or something, but there is definitely a bug with their system now. Cause I didn't pay. (and i checked my account, no charges. I have a gift card credit on my account and no credit card, so it would be easy to tell)
I'll update my post later if I get charged.
