I'd be kinda surprised. He might not use modern technology but some of his disciples do.
The Pope called together his college of cardinals and announced that he had some good news and some bad news. "The good news is that the advent is imminent. Our Lord will return on Saturday afternoon, 5 o'clock, Mountain time." One of the cardinals said, "But with good news like that, how can there be any bad news?" And resignedly he said, "The email came in from Salt Lake City."
Personally I think he'd be please, maybe not impressed but I cannot think that if there is a God and Jesus they are going to get about anything that petty.. certainly wouldn't hold it against me.
