Since ICS upgrade, I plugged the phone into my USB cable (hooked to the PC) and my headphones in to listen to music.Hit the Music Folder app shortcut (been using it ever since I got the RAZR because I hate the one that comes with).Little popup window says app not installed.Humm, it just did an automatic update the other day.So go apps - all apps, sure enough music folder is gone, so is astro file manager.Hit downloaded apps, yup both gone.So I unplug from usb, and download music folder again.ok, it's there, it works.I plug into the usb again, music folder is gone.huh?I unplug from USB, after a minute it shows back up again, so does Astro.There could be others that go missing, and come back.I could find this using search.Anyone else seen this?
