Data usage personal hotspot

Hi,

I did an update to io 4.3.1 just yesterday and the first thing I notice is dat when I used tethering on ios 4.2.1 I could see how much I was downloading and uploading in the blue pulsing bar at the top of the iPhone screen.
Now with ios 4.3.1 and personal hotspot the only thing it is showing is how many connections you have...
Is there a way to have those statistics again on top of the screen because I just used 1,6gb yesterday without knowing and I don't want to have any surprises on my bill

thx
