It will be interesting to see if this ends up being as abused as other warrant searches are. What is the probable cause of searching a cell phone? Does the guy have to have kiddie porn as his lock screen or is it enough to think he might have a drug dealer's home address in the phone book?
People's phones are almost their second homes, and in a way I am glad that the law is catching up with technology, but they need to be prepared for a whole nother set of issues that come with it
