From the beginning, BT promised to be a great solution for quick ad-hoc connectivity between devices. Early on, it became available for mobile phones, mostly in support of hands-free peripherals. Years on, and it's not only never reached its full potential, but actually receded in possibilities to a useless battery-greedy item that is best kept switched off. Maybe the reason for locking it down lies in the dangers of bluesnarfing, but in the new generation of smart phones it has become so restrictive and unusable that it's not worth bothering. Connecting two devices has developed into a lottery game. In 9 out of 10 times when trying to connect my iPhone to an iPod Touch, I ran out of patience. A slightly better ratio of approximately 8:10 applies to two Android phones. On the cross-platform front, after dozens of menus and setting parameters, I managed to discover and pair my HTC Desire to my iPhone, only to get an error message when trying to connect (see image). Such proprietary implementations of an otherwise near ubiquitous technology are untimely constipations in the connectivity channels we live with. It undermines an otherwise perfectly purposeful utility.
