iPad and iPhone do 60% of US mobile browsing and 8.2% of US web browsing is from mobile devices. These are pretty high percentages compare to five years ago. Then I looked at my mobile phone bills and statistics and I found out why. I was a Blackberry user since 2000; virtually hooks to it. This January I decided to switch to iPhone and rest is history! This is from my ATT monthly bill. I am glad I have an unlimited data plan; I am not sure about ATT though
