Dina wants to download her iPhone text messages with time and date. Leo says that the nice thing about the Apple environment is that they all work together. So the program that she uses for text messages, also works on the Mac if she sets it up that way. Then all the messages will appear there.
Another option is eCamm's Phoneview for $30. Dina can try before she buys and it will let her save all of her messages and data. They come in a PDF format when she saves them.
