Nokia E71 / E71x
Locking the E71
When the phone is unlocked, use the same buttons that you would use to unlock it (blue button and then immediately the function key)
Menu->Tools->Settings->General->personalizati on->One Touch Keys->Messaging Key-> and then either short press or longer press-> find and select "messaging" -> up to you which view you prefer.
As far as I know, there is no way to get threaded messages on the e71, unless you load 3rd party app, which I am not sure if it even exists.
Hope this helps.
Menu->Tools->Settings->General->personalizati on->Home Screen->Mode settings->Home screen applications->Application shortcuts
