Locked cell phones that were at one time inaccessible can now be unlocked using the latest digital forensic technology.  There is often a lag time between the creation of new technology and the digital forensic community’s ability to analyze it.  In 2015, digital forensic capabilities took a giant leap forward with the ability to unlock many cell phones that previously were not accessible.  Digital evidence contained in some locked cell phones prior to 2015 can now be recovered using new technology.
