Tachy, my understanding of the system is that your lawyer half lied to you--the court systems can do something, but it's going to run up considerable legal bills to do all the work to prove that it was her. You would have to go through all the hoops of getting a supeana for her phone records, and checking them against normal phone activity during the times of the harassing phone messages, and preparing this for an argument in court, and all the legal hoops her attorney would make you go through, etc. etc. etc.

Same thing for myspace--they should have IP logs of who logged into the accounts, and you could pull this information eventually, but it's quite a lot of work to get all the records made available to you.

If it's worth the considerable amount of legal fees that it would take to get it done, you may want to find another attorney to consult with, but you may want to just contact myspace to get the specific profile taken down.
