Find if 3G is enabled in iphone settings

is it possible to find whether 3G or Edge is enabled in the phone setting through applicati开发者_高级运维ons?

Its not possible to read the private Settings data (since apps generally can't access data that is not thier own), so I don't think this is possible. However, you can use the [Reachability] (http://developer.apple.com/library/ios/#samplecode/Reachability/Introduction/Intro.html) code from Apple. Also, you can try going through NSUserDefaults.
