iPad 3G will be a la carte
From Apple’s website:
So if you have a business trip or vacation approaching, just sign up for the month you’ll be traveling and cancel when you get back. You don’t need to visit a store to get 3G service. You can sign up, check your data usage, manage your account, or cancel your service — all from your iPad.
Man. I don’t know if I want to get the 3G one now. Feh.
