Installing the VZAccess Manager software and card was painless, and we were prompted to download the firmware upgrade for the available Rev. A service. The speed increase over Rev. 0 was noticeable: Both CNN.com and Gmail loaded in six seconds (essentially the same as if we were on a local Wi-Fi network). Downloading a 5.62MB file took an average of 39 seconds, and uploading a 991KB file took just 20 seconds.
If you're a world traveler, pick up the Cingular connection card, but if you want fast download speeds and the fastest upload speeds in the U.S. for less than $100, Verizon's Sierra Wireless AirCard 595 is the way to go.
