As someone asked for this I thought I'd compile a list of the available carriers plus APN settings in both the German 1.13 as well as the US 1.21 as found in the CarrierNetworkSettings.db3 database. I hope someone can use this.
I used a simple SQL JOIN clause to combine and match the results of the two tables com_palm_data_carriernetworksettings_DataConnectionSettings and com_palm_data_carriernetworksettings_CarrierNetworkSettings.
Interestingly the German 1.13 seems to have two more records than the US 1.21. I haven't checked which ones, though. If someone finds out, let us know, please.
XLS files zipped up.
