Good news, everyone [tm]
GPRS is by now in a fairly useful state. I've spent the better part of the last 3 days to fix all the remaining known bugs. It is working fine from a variety of phones including a G1 (MSM7200) , K800i (unkown baseband), TYTN2 (also Qualcomm MSM but with windows mobile), E680 (Neptune LTE), ...
The following parts are still missing: * Integration with the HLR, so every phone is accepted on GPRS * IP Header compression (ROHC) * Data compression (v.42bis) * Authentication (depends on HLR integration) * GEA3 Encryption (though most of the infrastructure is there) * Ability to route APNs to different GGSNs
So everyone who has access to a nanoBTS: Try it now. The build/config instructions haven't changed from what I described last time when I wrote a GPRS status update to this list.
Happy hacking, Harald
