Perhaps, but if you are taken to a conversation regardless of how you launch the app (ie, the previous state, which is standard behavior), then I would say, no.

Perhaps, but if you are taken to a conversation regardless of how you launch the app (ie, the previous state, which is standard behavior), then I would say, no. Which is what is happening in the Google Voice application. I should state that what actually happens in this scenario is this. 1. View conversation, leave Google Voice. 2. Re-enter Google Voice somehow, currently viewing conversation. 3. Hit back button, taken to wherever you came from (previous app, home screen, etc) 4. Re-launch Google Voice, now the starting screen is the inbox.
