Tethering on Android

[PiKe]

Normally networks would like to charge for this service.

I personally don't make use of it myself but I've always wondered what if I wanted to use it in an emergency, if there's a power outage and I only have a laptop.

Is tethering detectable by the operator? Data goes through the same APN so I'm not sure how it could be?

I'm on a Vodafone contract so if anyone could say one way or the other, that would be most useful.

All networks can detect it (it stands out pretty easily) but no network is clamping down on it for now as it's not too widespread. The reason it was controlled on the iOS before someone tries to jump me is because iOS network control setup is OTA and easy as hell to do, Android has no native OTA setup system so the networks can't control in-use features etc... Unless they use a network specific rom with the option taken out.

How is it detectable? Just by the headers sent by the web browser?
