They do have some devices that are in use in larger metropolitan areas. These devices are in use by VZW and partners of VZW for testing purposes. They have some devices that are already made for it such as MyFy (personal wifi) and we should start seeing these availiable to the masses around the middle of next year
If they slipped WiMAX capable radios into the Droids that is news to everyone since it has been dissected and if there was a WiMAX radio on there it would be front page news on every blog!
Sprint brags about having the worlds first 4G network....well that was because they also had the worlds first cell network!! Based on how long they've been around they should be at like 8th Gen, so they are WAY behind and shouldn't be bragging about it!
No matter what technology VZW decides to use for the new network it will more than likely require new hardware. While I would love the droid to just jump on the new system when it gets switched on, more than likely that will be saved for the Droid 2....or 3 depending on how long they actually take!
This is something that they already have test networks up and running.
The supposed speed is somewhere around 25Mbps MAX, but when a few 3rd party companies where doing testing the fastest they could get at one point was 22Mbps.
Its coming to Verizon, its just a matter of when and $$$$ to develop the infrastructure.
