- Install the APN while I'm in the air, which I plan to save in an email.

- When I land in Newark, I should, if everything goes right, have internet access!

Don't forget that AT&T will be able to see what you're using by the IMEI being broadcast. I've heard of people attempting to use an iPhone on a GoPhone account only to have it quit working after a period. Officially AT&T doesn't allow iPhones on GoPhone accounts. What may work or may not work always depends.
