Here's a great way to record different voicemail messages for different people that call you. Youmail works with T Mobile, Cingular, and Verizon currently. The way it works is pretty simple. You set up an account, log in, and begin recording different messages that will then be played when certain numbers call you. This would be great if you used your phone for both work and friends.
Another neat trick of Youmail is the ability to save messages, and to then email those messages to people. So if you get an important call from a client you can fwd it to your team. OR on the flip side, if you get a funny drunk phone call from a friend, you can fwd it, or post it on your site. HOW fun is that!
