YouMail is a free service that lets you change your cellphone's voicemail greeting according to who's calling. You could record a separate personalized voicemail announcement for every entry in your phonebook.
So now you can sound businesslike when the boss calls but get jiggy with the troops when they peep. YouMail's web-based interface lets you access your voicemail online and e-mail it elsewhere, too. So far, it's compatible with cellphone service from Verizon, Cingular and T-Mobile.
This could be the next ring tone-like feature for cellphones, letting you be you. Sounds like fun. Get it while it's still free.
