Just got this reply from 02 about the internet access on the iphone.:
Thanks for emailing us to find out if you can access Internet using your own BT broadband account.
I'm sorry you won't be able to access Internet using your own BT broadband account or using a broadband account offered in a coffee shop. This means that you won't be able to access Internet using a broadband account in or after your 12 month of free Wi-Fi access has ended.
You can also visit our website using the link given below for the most up to date information on iPhone:
