Is it possible to troggle between 3g and edge through an app and not closing the app and going 开发者_StackOverflow社区to settings?
No, this isn't possible via the SDK. The choice between 3G and Edge is a user choice, (provided that 3G is available and there actually is a choice) and not a programmer choice.
You may get away with it in on a jailbroken phone, but not via the official SDK.
