So my current thinking is to introduce a method to NetworkRegistration 
property called 'ProposeOperatorScan' and a new property called 
'OperatorScanInterval'.  The driver api can then support a (non-standard 
*gasp*) option to say whether this scan was initiated actively or not.

Maybe the Nokia modems can use this information not to drop the GPRS link if 
it isn't an active scan being performed.
