I don't know about real life but as per Jackson's "twitter" he tweeted this yesterday:
Dr. Jackson Avery @JacksonAveryGSM 8h
@StephEdwardsGSM @JoWilsonGSM Just landed. FYI they have twitter access in Houston. You can cure maleness with a new thing called surgery.
I guess he is at a conference...maybe that comes into play later, I have no idea. It's a pretty cute conversation tho. He asks Stephanie and Jo to tell him a joke while he is waiting for a cab and Webber scolds him to stop distracting them
