I have a new Verizon Iphone 4. I downloaded Speedtest.net. Here's the idiot question: What are results indicate good speed and bad speed? Also, is it better to use kbps, Mbps, or kB/s? My most recent test showed the following results: Download: 1838 kbps Upload: 580 kbps Ping: 198ms Are these good results? If anyone can provide reference numbers against which I can measure my results, it would be very much appreciated. Thanks for your help.
