...But some phones are already smarter than their owners

Researchers at Carnegie-Mellon University are working on a smarter, more polite cell phone. Phones that will ring loudly if you're in a noisy environment, or vibrate when they're in your pants pocket. Phones that will sense when you are conversing with someone and text back the caller telling them that you are busy right now, but if it is urgent they could try back within three minutes.

Sounds like these Indian cell phone owners should have volunteered for beta testing...
