Since the latest update of Listen, my phone seems to shut itself off when I'm listening to a podcast and I get an email notification. This happened once yesterday and then again this morning on my way to work. Actually it's more like it locks itself and becomes unresponsive. I have to remove the battery and then power on again. Yesterday I couldn't see it, but this morning the buttons lit up and the led blinked even when it was locked up but the screen just wouldn't come on. Anyone else out there using Listen and have this happen to them?
