On forum.nokia I found this form nokia unanswerded thread:
There is mentioned, that 3rdPartyTelephony is missing on Nokia 6600 which uses Symbian 7.0.
The older gsmbas is in this version depraciated and to establishing calls and - what my aim is - getting the cell Id you have to use the 3rdPartyTelephony. I'm programming for Symbian 8.0 i.e. Nokia 6630 and the app doesn't run on the phone. Knows somebody something about this and is there a firmware-update available? Is there an other way to get the cell-id?
Please answer me!
