Earlier today, everything was fine. I was connecting via wifi and t-mobile 3g. Before I left work, I noticed that there was no active connection (strange since my office is always in a good network coverage area and there are 2 wifi networks there).

When I go to the quick settings menu and click on "Internet connection" the quick settings menu just closes with no other feedback.

From the Settings page, under Internet Connections, I haven't changed anything. It's set to connect to anything available.

I've rebooted several times, left the battery out for a few minutes, and even restored the factory settings. dmesg doesn't show anything strange.

I can call out with no problems, but this thing will not connect to a data network. I didn't want to have to flash it, but I think I might have to.

Any suggestions?

Update: In addition to the network settings not showing any sign of response, I now find that the sd card cannot be read.

When I run an ifconfig command, the only interfaces I see are lo and phonet0. Tried an ifconfig wlan0 up and I see the wlan0 setting, but there's still nothing going on.

Flashing it...
