I am using my phone's built in Wifi Hotspot to share wifi with my laptop and my other devices. I am using android 2.3 (Gingerbread), and the phone I have is the HTC Desire Z.
Is it possible for a carrier to detect that I am using "Wifi Hotspot" and sharing my mobile data connection with other devices?
Furthermore, is Wifi Hotspot a feature that most android devices have? and is it a feature that can be disabled by the carrier (on a phone-by-phone basis)?
