Here it is, my 32GB White iPhone 4S on AT&T vs. my mother-in-law's 16GB White iPhone 4S on Sprint. The location is San Diego and the video is crappy (so sorry). I rushed this to the internet and will try to upload better quality videos later. This was shot on my Canon S90 in low light.
Testing the new iPhones in San Diego, California, I have two brand new iPhone 4S working on their perspective networks, AT&T and Sprint. Both caches, cookies and histories were erased and I loaded up Briam Lam's The Wirecutter and from there navigated to various parts of the site (MacBook Air Review) as well as load up a link to Jason Snell's MacWorld Review.
