Hallelujah the phone appears to be alive, still able to gasp out a GPS signal, and only 1.3 miles from home!
FORBES: How A Dorky Holster Saved My iPhone In A 60 MPH Accident
We tested the device indoors -- located near a window, it picked up a GPS signal easily, and transmitted its location to a map within the iOS app even as we walked 100 or so feet away, past several walls.

It's designed by former Nokia engineers who claim they've used their mobile skills to make the Leikr catch a quicker GPS signal, connect directly to a cloud-based, Endomondo-integrated exercise portal using WiFi and Linux-based software, and at the same time stick to a smartphone-like 10mm thickness.

It combines a conventional global positioning system (GPS) signal with those of other sensors - accelerometers and gyroscopes - to pinpoint a car's location to within 2m (6ft 6in).

Her husband carried a GPS device, which sent a signal every five minutes.
Our standard battery rundown test involves setting the brightness and volume to half, using 4G in a 75 percent or better signal area, enabling GPS and WiFi (not connected) and disabling Bluetooth while looping a video from a full charge until the battery is drained.

When a signal bounces back from the GPS-enabled device on the Earth, it can tell exactly how far away that device is.
However, GPS signals can fail or be fooled by a conflicting radio signal, said Professor David Last, an advisor to the to General Lighthouse Authority.
According to Navsys, the company that developed JLOC, it involves a network of GPS receivers capable of detecting regions of higher than normal signal levels and low signal-to-noise ratios, either of which can indicate interference.
The basics behind Loran and GPS are largely the same, with devices measuring the time it takes for a signal to travel between a transmitter and your receiver.
The plastic was also a necessity after the all-metal body of the Transformer Prime resulted in widespread GPS and WiFi signal problems.
He also said the court clearly sent a signal to Congress that a federal law is needed to clarify when and how the government can conduct GPS surveillance.
The captured data is then encoded with GPS info and immediately sent to a call center or trusted friend, or stored for future transmission if a signal is not readily available (since you need to reenter a coverage area at some point for this device to be effective, we can safely rule out T-Mobile as a potential carrier).
