Hello and welcome to the forums, unfortunately I don't have the correct answer as it would require jailbreaking your device to actually work. Someone with more experience will be be able to assist. Again welcome to iMore!
If you're on iOS 6.1.3 or above, there is no hope. Most versions below that can be jailbroken, a process which will void your warranty, but allow you to do more things to your device, including adding those features you mentioned.
