What hardware will the Ubuntu Mobile OS support?
Is there any plans to make Ubuntu Phone OS run on jailbroken iPads, iPhones, and iPods? I know someone managed to get Xubuntu running on an iPod touch once so I was wondering if Ubuntu's Phone OS will run on iDevices.
No it won't. Jailbrocken iDevice are only just having root access the device.
The bootloader to these devices are locked and they will only boot iOS.
And also the android phones whose bootloader are locked can't install it.
