[Commotion-dev] Boilerplate Android code pushed

I poked around a little bit, my /data/misc/wifi/wpa_supplicant.conf file
seems intact.  "netcfg tiwlan0 up" and down no longer work, it tells me:

# /system/bin/netcfg tiwlan0 up
action 'up' failed (No such device)

I rebooted and cleared the cache, no luck there. I'll try flashing CM7.1
again.  Do you have a phone you recommend for wifi hacking with Android?
 We have a good collection, so we probably have a better one than a
Droid/Milestone running CM7.1.
