Same problem here. Qi can boot only for SD card. I use u-boot in NOR for
booting from NAND.

Yes, this is known problem. Must be something missing in debian rootfs
or some other small diference, because it should be working on FSO based
rootfs. I use terminal and iwconfig for wifi connections now.

GPRS works for me. I just set APN, dummy username and login. This time
it connected on the first try. Sometimes i have to retry.

Patches are welcome :)

Yup i also noticed that the cursor position is not correct.

I am working in my spare time (so it's not very much). I am planning
possibility to run X apps. If that works out we will get a lot of
applications. I will fix all regressions, but probably not enough time
to fix all bugs. I see the future quite bright. We are regulary
importing new QT releases so QtMoko will keep to be easy-to-develop
platform for QT applications.

Would be nice to see the results.
