i just got the mango update today, switched from my iphone to the trophy but now i have no 3g connection. i've rebooted, pulled the battery ... nothing works so far .. maybe it will take a while?
i had to reset my phone to get 3g back .. not the ideal solution but it worked!!
Cool, I had the same problem when I got the Mango update too. I'll give it a shot.
according to wpcentral, the htc connection app is the cause, if you are going to update uninstall this first.
they also have instructions on how to force the upgrade, and yes it does work
and a personal thank you to verizon for the amount of time you just wasted for me by not testing
