any device transmitting a signal can be tracked is all i know.

Sure, how about constantly changing IMSI? I think someone managed on Symbian...

However as it's now clarified, let's get back to topic. This is a whole other discussion to be held elsewhere :-)

I still hope you find someone capable to help you out!

Cheers

CodeRUS managed even to change IMEI on symbian, and you're right IMSI too

Now this is fairly pointless I can assure you!

If you "constantly change your IMSI" sure yeah network will not be able to place you but what good is it going to do to you?
You cannot receive or initiate any calls, and that includes both IuCS and IuPS...

Easier to just take the battery off from the device.

doesn't the software that allows to track (and / or wipe) the N900 in case it is stolen use silent SMS?
