So who will make the first app that lets me strap my iPhone to my back wherein its sensors feed a program on the device, or more Siri-like on a remote server, that keep me upright after swilling pints all afternoon?

I guess version 1.0 has a backpack with a segway-like bundle doing the heavy lifting. Version 2.0 communicates with my inner-ear to hack my natural mechanism for balance.

Anyone for kebab tonight?
