Sprint Everything Data does not allow tethering

[ScottHarris]

I just got a new Samsung Moment for my wife and our bill went up $129 a month. I was told it is because you are required it have the everything data plan with this phone. We have the everything messaging (texting) plan and added on a few data options to allow for tethering. According to Sprint the everything data plans does not allow you tether your phone which I assume means no internet sharing of any kind.
This leaves me with a few bad options
1) Return the phone that my wife has waited a long time for
2) Move all phones to the everything data plan and lose my ability to use the phone as a modem or pay big bucks to do so
3) Split the account into separate plans. The cheapest data plan for that phone is $69 and then I still have my $125-$150 plus for everyone else, again big bucks I do not have
4) Find another carrier that will cost more but allow me to do what I need with the phone. I have been with Sprint over 12 years and hate to leave but I am forced to upgrade to features I will not use (Sprint TV, Navigation, etc) and lose the features I have grown to depend on I am not sure if
Right now I have a mogul but was going to upgrade to TP2. The TP2 requires the same thing so I am not sure if I can afford to move now.
Anyone else have a similar issue? Is there anything that can be done to get the TP2 to tether and not violate sprints policies? I searched the forums and this appears to be a little unique situation.
