Among the files left untouched was a 500x333px image from flickr and some of GoogleвЂ™s map tiles. ThatвЂ™s less than 50% of the original size, despite the fact that five of the images had been left untouched. The savings were significant: the images downloaded via WiFi totaled 2.1MB, while the same images fetched over Verizon totaled 796KB. Of the fourteen images I downloaded, nine had been altered by Verizon. I ran my app once on my WiFi network at home (connected to the internet via Comcast) and then again with WiFi disabled, using VerizonвЂ™s data network.ДЇinally, I copied the images off my iPhone using Xcode. The URLs I selected were all images in jpeg or png format from my own web server and a variety of well known websites, including Apple, Amazon, Google Maps, and Flickr.

Rather than simply trust Verizon, I decided to empirically test the effects of its optimization process.ДЇor my experiment, I built a simple app for my iPhone 4S that would download an uncached copy of a list of URLs.

Verizon claims that the information it removes from images and videos is conservative, for example by removing only colors not visible to the human eye. It turns out that this process actually works by intercepting data sent to your phone, particularly HTTP data over port 80, and applying lossy compression before passing it along to you. Earlier this year, Verizon Wireless adopted a process it calls Network Optimization with the goal of more efficiently transmitting data to its customers, and thereby reducing the load placed upon its wireless data network.
