I just purchase another house and I've been doing some work trying to get the garage together and I noticed this thing up high on the wall. It appears to be phone related or maybe not. I'm sure there is somebody here who can help me out. My other house did not have this thing as it was built in 1985. Just trying to learn. Thanks in advance for the help and sorry about the bad pic. Its an old iphone.
Hey, lucky guy could have had a furnace in his garage.
