It's been available in CA for about a year, but it has a two caveats: you allow them to autocharge, and you stop getting the paper statements.
What I need - and get from the most places - is ability get a paper statement and to pay it with a credit card online. Autopay is the worst - you pay first and then try to get your money back, very weak negotiating position!
Besides, who has the discipline to review your phone bill online?
