Local Bluetooth device address??

Hi!
I'm having problems with local Bluetooth device address. My code works fine in older phones, which uses Symbian versions 6.1 or 7.0 (for example Nokia N-Gage and Nokia 6600). But in 6630 it doesn't work. The C++ code is:

iSocket.Ioctl(KHCILocalAddressIoctl,iStatus,&iDevAddrPckg,KSolBtHCI);


I know that Publish&Subscribe API can be used in 6630 to find local device address, but it is not compatible in older ones.

So is there a way to get local device address so that it works in every version of Symbian OS??
