Track your iphone (or other device) by sending location emails or location text messages to other cellphones every 15 minutes.
Use this if your phone is lost or stolen, or if you want to let someone really know where you are.
Anytime someone (or you) uses your device (with coJack running in the background), you will receive emails every 15 minutes.
CoJack (when running in the background) can:
> track a lost or stolen iPhone (or other device)
> email someone your location (not everyone has an iPhone)
> txt someone your location (not everyone has internet access)
"Continued use of GPS running in the background can dramatically decrease battery life.
