Hi Holger,
Update some information, and move to devel list.
I found:
Release rootfs + asu.dev Aug 03 kernel:
I can see GSM signal
I can dial/receive calls
Release rootfs + release kernel:
I cannot see GSM signal
I cannot dial for "Not registered"
BUT I can receive calls O_o;
It's really strange enough.
Do you have any idea?
Cheers,
Tick
