Wee, finally able to inject RIL commands on Android devices.

There are some drawbacks though, first (of course) root is required. The second is a little more annoying, on HTC devices this will cause the device to ask for your PINcode (so you have to turn that off). Doesn't do that on the Galaxy S though!

So this makes possible (for example) an actually working 2G/3G switch widget (one that does not just send you to the settings screen). Now if only I knew how to build widgets ...
