Of course, if you go beyond the official SDK documentation, all bets are off once you start to consider what might happen with newer versions of the Android platform on the same devices, or on devices from a different manufacturer, or using a different chipset, or using a different protocol to communicate between the application CPU and the baseband CPU.
There's nothing wrong going to see what happens "under the hood", as long as you understand that you're leaving the realm of the SDK with its supported APIs that are meant to stay compatible across versions and across devices, and that peeking under the hood is nothing more than anecdotal data on implementation details about which no compatibility is guaranteed or even implied. Discussions about what happens under the SDK APIs are probably better suited for the android-platform mailing list, such that this list remains dedicated to discussions related to developing applications on top of the SDK APIs.
