After reading:


S40 devices return cell-id by property "Cell-ID" BUT
it works only for signed midlet by Nokia or operator.

As I know Nokia signs each Midlet before put it in Ovi Store.
It means that apk. will have access to this property after signing by Nokia ?

I would like to create application for S40 devices which uses cell-id to
track some objects on the map.

Of course theres is API Location (Jsr-179) but probably none S40 device
has GPS on the board. It needs to be supported by external device.
