Jailbreaking your device allows it to run non-signed code that wasn't reviewed by Apple. It has benefits, such as the ability to run apps that aren't accepted by the AppStore, but it also opens up your device to malicious apps and bugs that are hard or impossible to detect by us, the app creators.
It also allows apps to communicate between each other in ways that Apple doesn't approve, and with good reason: this non-authorized communication may cause problems to your device and your apps.
That's why we at Movile do not support Jailbreaking devices and we can't offer support of our apps when installed on Jailbroken devices. If you have any problems involving our apps on your Jailbroken device, we recommend removing your Jailbreak before contacting us.
