- 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.

Mine's been in the US several times (I forgot to mention using it in San Diego in February for a week in addition to Buffalo and Boca, and I used it in Rapid City, SD in September too). No issues yet. Obviously I can't state unequivocally that it won't be a problem but it hasn't been for me.

It wouldn't surprise me if AT&T had this attitude and policy with its own locked iPhones. My iPhone 3G is a Rogers iPhone (software unlocked; official unlock will happen August 1) and my iPhone 4 was bought unlocked from Apple.
