A-Patch to remove the "says:", here's a screenshot:
I think it would be better to have the name and message on separate lines, because some contacts have long names so it would become hard to read. Example:

ThisIsAContactWithAVeryLongName-BlahBlahBlah says: How are you?
...You get the point
But I don't know if it's possible.
