is wery like now#

So what I wanted to say was I’m from Australia and I can concur that the MSISDN provided in the Header is controlled at the WAP GW. I’m quite sure all the phone providers in Australia are blocking this info. It’s either privacy laws or greed. Why I say greed is because they want to be able to sell this information to companies etc.

To an extent ‘yes’. It masks your UP address and all custom headers sent through your mobile device. Of course, Opera still gets this information as all your data and requests pass through its servers. Additionally, surfing through Opera Mini allows Opera to track your surfing habits. I guess it is still better to trust Opera rather than trust arbitrary websites with your identifying information.

Hey Rohit,
Do you mean that using Opera mini would somewhat protect our privacy..?

From what I know, this depends on the Mobile Operator. I had got the headers mentioned above from Airtel AP during January last year. Donâ€™t know if they have rectified this yetâ€¦

I also tried this with my friends iPhone on a AT&T connection and it doesn’t leak any headers to websites. Guess it is just a matter of properly configuring your gateway.

I tried your code and got a blank value for all the unusual headers. I tested it with a few of our Nokia and Sony devices. I dont think the number is transferred. Or may be only with a few devices.

The complaint falls on deaf ears here, I tried reasoning with Airtel and all I got was a huh?

I think I understand what you mean here. Most of the phones that I have encountered use something like a WAP proxy to communicate with the websites. The Treo on the other hand doesn’t have a setting for a WAP proxy, rather has fields for just an assigned IP address and a DNS server address; so I reckon that the procedure is different.

Thanks for bringing that up!

As I said before, the treo is likely NOT configured to send its packets throught the gateway. Hence, the gateway does not see the packets and is therefore not able to insert the headers.

BTW, if I were your friend, I would call the wireless operator and complain about this information being sent out. The WAP GW can be configured to only share the information with specific websites. It sounds to me like the wireless operator had some kind of deal with particular websites or even a website of its own, to share the MSISDN/IMSI. However, the operator got lazy and instead of provisioning the gateway to share the info with just one website, it just provisioned it to share it with all.
