For now at least. so what about the magic CDMA + UMTS combo chips. We basically have to reload the firmware with these. Would be nice to figure out on how that can be done. Not that we know much about how Qualcomm intends to use that in a phone case scenario, but would be nice to at least think about it a bit. Also I wanted you to ask about the data roaming. Does the Nokia modem has an option to NOT data roam that we can set. The problem with doing it in the host is that a bit of data goes through if you start roaming and have a PDP context active. So it costs the user. At least some reports indicate this. Does your modem forces a detach or does it just happily data roam and just give us a cell update? The AT command specification obviously didn't care about this at all :( Regards Marcel --===============1443109549117177852==--
