Uhhh...you'll either have to hope that the neighbors have an unsecured wireless network that you can steal (by turning on your wireless card in the laptop, opening up network connections, choosing wireless network connection, show list of networks, and connecting) or get internet service at the beachhouse. You could probably get some cheap dialup set up since you have a phone line. As for the blackberry, I have never used one before, so I have no idea how to set that all up. Good luck! ;)
