I recently found this, although I haven't had time to completely test it out yet. I figured I would let you know about it while it was still free!
Website YouMail is the new voice mail for cell phones. Among many features, it allows you to record unique voice greetings for anyone who calls you, based on their caller ID. Individualize your voice greetings for friends, family or important callers while maintaining a standard greeting for work and unknown callers.
Check your voice messages from any phone or via the web and forward favorite messages to anyone via email. Have fun with the already infamous DITCHMAIL feature that hangs up on unwanted callers after your custom greeting for them is played.
YouMail works with your existing phone and carrier and is easy to trial without risk. YouMail is free for users who sign up now while there are still beta accounts available and easy to change back and forth between your current voice mail and YouMail.
