<snip>I can't see getting rid of land line phones for just a cell. <snip>
Rastus, you are correct that anything "broadcast" does not need a search warrant, but while I'm not sure about this, I THINK, that even land line communications get broadcast at some point in their journey.
during the 2004 hurricane power outage, the cell service went down about the third day of the 9 day power outage... I still had POTS (plain old telephone service) via land line for the entire 9 days.... if you have never looked, your exterior communication box should have a plug in for a phone... maybe even your neighbors
Just thought I'd share my home phones.The one on the right was my family phone back in 1955-1962. The other one was ours for a very short time after that.
