Hi,

Any success with GPRS usage, and any possible problem points that were
resolved by you?

I've followed example files at both
http://wiki.openmoko.org/wiki/Manually_using_GPRS and
known-to-be-working from my previous phone (though via bluetooth to
laptop, device name changed etc.). gsmd is disabled and I've manually
disabled/enabled GSM power via
/sys/devices/platform/neo1973-pm-gsm.0/power_on.

The best I can get is:

+++
OK
ATZ
OK
ATE1
OK
AT+CFUN=1
ERROR
Connect script failed

or if using more what I have used before:

AT
OK
ATH
OK
ATE1
OK
AT+CGDCONT=1,"IP","internet"   # <- the AP there is right
OK
ATD*99#
ERROR
Connect script failed

Another symptom is that if I get that far, it's always that every
other time nothing happens (Connect script failed after some time),
every other time I get that output.

Have you experience something similar and found out what's the
problem? I've fiddled with both gprs peer settings and the
gprs-connect-chat scripts, adjusting timeouts and everything, but no
success.
