Depends how much I'm at home - then I only use Wi-Fi.

Actually, now that I am thinking about it. I'm sure this is why my data usage is so low. I mainly watch netflix and other things on a wifi connection... I feel kinda stupid now.

I use about 1.2 to 1.6GB's a month and I'm always on 3G unless I need to update a big app or Facetime. Since my 3G speeds are incredible, I prefer to stay off of wifi due to wifi shortening my standby time of battery life

2-5 gb a month. it varies due to how much tethering i allow others to do on my MyWi and lately i've been raping my Netflix account to death

still haven't received a letter so FU at&t!

In the first 21 days I had with AT&T, on a BlackBerry Torch, I used 200mb of data, then I get my i4, and I've used that much (if not more!) in less than a week with the i4, going back and looking my months when I had an iPhone 3G on T-Mobile, and then fast-forwarding to my usage these days, I'm guessing I'll use around 1GB per month.
