iPhone call forwarding indicator

Ever since I started using my iPhone, I wished it had a call forwarding indicator. I typically give out my cell number as my main number when meeting people, and then forward the iPhone to wherever I am. Sometimes, I forget to turn off the forwarding when I leave again, making me unreachable.

To my delight, I discovered that since upgrading the OS to 3.0 my iPhone 3G now indicates when the call forwarding is active with an icon on the status bar.

I haven’t seen this feature announced, so I am not sure if it is part of the overall 3.0 package, or if it is a feature specific to my carrier: Rogers Canada. The screen shot below shows the phone with the indicator on.
