My Dell Streak, running official 2.2 after OTA update a few weeks ago, is suddenly refusing to turn on the radio for wireless/cellular voice and data. I have restarted, restored to just after 2.2 update etc, but still no 3G radio. It does not even try to read the SIM card, that works just fine on my old Samsung Galaxy.
The Airplane mode check-mark comes back on after trying to enable wireless connection.

All OK after help from Dell France support to download and install latest update package, 131800
