You could contact the people who made this

It only works on jail broke phones, another way it to use push notification from our servers for timed tasks. Why dont you use this, to wake up the app get the GPS then send it back to sleep. Better for batteries too.

Answer 3

I don't think this is allowed in the iPhone programming paradigm. The operating system is capable of running background tasks but ordinary iPhone apps are not permitted to launch anything like this.

Answer 4

I think you are in one of cases you can do background process, take a look in this discusion

Run app for more than 10 minutes in background

Answer 5

Not possible without jailbreak - iphone sdk apps can only run while on screen.

Answer 6

The Apple Push Notification service is not, in fact, only available to a few developers. It is currently in wide-spread use.

Take a look at this:

http://developer.apple.com/IPhone/library/documentation/UIKit/Reference/UIApplication_Class/Reference/Reference.html

The "Registering for remote notifications" section specifies how to register for push notifications. The other end is set up in the iPhone developer portal.
