I'm using an unlocked (not rooted) Motorola Milestone (Android 2.0).
When I start up Messaging, go to Settings and choose Manage SIM card messages, a list of text messages on my SIM-card appears. When I hold my finger on one of the messages a menu pops up that allows me to "Copy to phone memory".
That's what I did. I copied a few of those messages to the "phone memory", but how do I access them? I can't seem to find them in the Messaging app.
