I'm at 500mb a bit over halfway through my first month. I stream wunder radio about 4 hours a day at work though and then more at home....
 
First month with 3GS. I estimate I'll be using 1-2GB per month based off usage.
 
i haven't seen how much i today (which was alot) but earlier i was at 2.2 gigs sinc june 22. so all in all i will say 3.5 - 4 gigs a month for me. alot of audio streaming at work takes up most of this. also emailing videos isn't helping either.
 
According to my last bill, 3,176mb so roughly 3gigs. Its mainly because I listen to streaming music at night on 3G, a 256kb stream at that :D
 
How is it "ridiculous?"

I'm up to 7.5GB now.

at least what i can tell is, if you listen to alot of streaming music then this will add up fast. think about it, not everyone has access to a computer where they work, throw a radio with a dock connector or "line in" option and BAM internet radio at work.:)

i do this myself. although roughly 25 out of 40 hours a week is taken up with podcasts.
