I was fortunate enough to have a GUY pick up the phone, not the "lady"
Hypothetically speaking, I asked since (lets say 3.851) says its the latest software and I do not see an upgrade price, will they upgrade it to 3.872 free of charge? He said no. I said what about 3.864/868 which are the last right before it. He said, no, I would still have to pay the cost... I said how much even for those versions...
