I think the defense can ask that all testimony using TM cellphone records be struck because they are incomplete.
Or use the introduction of the cell phone as a way to open the cell phone evidence to the jury
If they don’t have a voice authentication report on Trayvon’s conversations with Jeantel, that testimony should be struck, as well. After all....no authentication, no admissible evidence. It’s just her addled ‘perception’ that it was actually Trayvon she was speaking to. And that same somebody that must have snuck in and sent all of those texts could also have faked Trayvon’s voice on those calls. Right?
