It sounds more like d= isabling one modem and enabling another. And I'm sure there are other areas= in the API that are going to need tweaking for CDMA.

That is what T-Mobile promises me when crossing borders into Netherlands or Austria with my German SIM card. It should have smooth data roaming. To be honest, I have never really tried it. Either I was on a plane anymore or too cheap to pay for data roaming ;) Regards Marcel --===============4967538242190081963==--
