Tailor your cell message to the caller

Here is a clever idea: Tailor your cellphone voicemail greeting to the caller, based on caller ID. You can do it with YouMail. The service has other nice features as well, including enabling you to check voice messages via the Web and forward them by e-mail. A “ditchmail” feature hangs up on unwanted callers. The service, still in beta, is free for now, but new accounts are limited.
