The back button should follow the users path; if I'm in an email, then a click a link, and then get an SMS then the back button should take me from the SMS message, back to the browser, and then back the email.
However, applications need an additional bit of UI so that from the SMS message you could go "back" to the list of all messages, etc within the app. It sounds like, on Android, there is some confusion between these two use cases and other issues that make it unreliable. It's a shame because the concept is sound.
