iphone settings accessing

It is possible to change iPhone settings from an application? I want to c开发者_如何学运维hange settings like enable/disable WIFI, enable/disable vibrations, change ring tone, enable/disable bluetooth, call forwarding, mail accounts, etc. I want to be able to change all settings programmatically. I would appreciate some sample code.

It is not possible with the current SDK.

No, it is not possible to enable/disable WIFI,... with the official SDK.
But it is possible with a jailbreak! There are a lot of apps at "Cydia" to make low-level settings.
