if your devices were done via remote then throttle was/is possible,we only gaurantee dethrottle thru mail in,the 2200 remote dethrottle was added into the firm as a beta to be tested for a while to see how long it would last,i posted that in the forum the same day i added it the firmware and i know elisa has posted it as well,it has not been proven yet,thats what a beta is.

so ask yourselves if that is your situation,i have had 2 2200 running,one vzw and one virgin mobile,i flashed them when i first made the dethrottle and they are still fine, our 2200 mail in service dethrottle is working great,and as for your guys's speed going up and down,thats not vzw testing or what ever it was that was said its because your using a wireless device nothing more, all mifis do that
