As I understand it, I don't think they can recreate actual conversations from a phone or data. Anyway, telephone conversations, just like face-to-face conversations, are not admissible as there is a reasonable expectation of privacy. Anything else is admissible, including texts and emails, though.

Data can and has been seized which would provide all kinds of information such as phone records, purchases, locations.

Carrying a phone is pretty much carrying a very, very thorough tracking devide.
