This afternoon I ran a simple test.
On my Android phone I used the browser to go to each carriers home page. Below are the results for each web site. What’s amazing to me is that only one carrier actually detected that I was using a mobile browser to access the site.
T-Mobile is the worst offender downloading almost a meg and a half of content.
Verizon gets it. Put a simple page in front of the user and do it really quickly.
