I recently bought an Audiovox PPC4100 and unlimited wireless internet service from AT&T. I noticed today while talking to my wife on the phone using the headset and surfing the web at the same time that pages downloaded much faster than when I am not talking on the phone. I was just courious if anyone knows any technical reason this happens. Normal web surfing on my pda is about how I remember my old dialup service at home but while having a phone call connected the pages downloaded more like my DSL I have now.
