I use the follow code to get the APN config

QNetworkConfigurationManager manager;
QList<QNetworkConfiguration> allConfigurations = manager.allConfigurations();

while (!allConfigurations.isEmpty())
{
QNetworkConfiguration config = allConfigurations.takeFirst();

if (config.type() == QNetworkConfiguration::ServiceNetwork)
{
foreach(QNetworkConfiguration i ,config.children() )
{
qDebug()<<"G" << i.identifier()<< "|"<< i.bearerName() <<"|";//<< i.name();
}
}
else
{
qDebug()<< config.identifier() <<"|"<<config.bearerName()<<"|"<<config.name();
}
}
the N900 console print

IAP "联通GPRS连接互联网" network type is not set! Skipping it

"0f31837c-c525-4c63-8bb2-5f28d7b8aa7a" | "WLAN" | "zhpublic"

The first line mean? I use the China unicom 's SIM card, according to n900 system network config ,it should be IAP "china unicom (in chinese) GPRS connect(in chinese)" .

How to get this gprs 's identifer?
