I'm not getting offered an update at this time through my phone or through Zune when manually checking for an update either, but I'm already to 7.0.390.0 because of the little network cable trick a few weeks ago. Hopefully my phone isn't stuck at this version now, though it may be possible to restore it back to factory settings and attempt to update again.
