If you ever tried to access any AT&T wifi hotspot in starbucks you would be welcomed by a friendly page asking for your login information and/or credit card to access the internet using their service.
You can refuse to pay and still remain connected to the wireless network yet cannot browse the network. However, you’re able to get updates from Apple?
Strange yet interesting. There may be a possible way to access the internet withough paying AT&T.
I hope this inpsires someone to find a way how.
