As Dustbak mentioned, this can be accomplished with using a CF/CFII or Ixpress series Hasselblad digital back. In addition, this can also be done using an H3D/H3DII digital back as well.
Bear in mind, the latest firmware versions for the H-series camera bodies can only be installed via Phocus. FlexColor is not compatible here. Additionally, the Imacon/Hasselblad Ixpress backs are also not fully compatible with Phocus. In short, your best bet is find a CF/CFII or H3D/H3DII back, the latest version of Phocus, current firmware from Hasselblad, and someone familiar with the firmware upgrade process.
Considering your location, I would suggest you find a local Hasselblad dealer, as they will most certainly be able to take care of it. With the right items (see above), this process will take just a few minutes, and should be of little to no cost.
I have attached a PDF copy of the readme file associated with the latest version of H-series firmware.

I have both an H1 and H2 along with a Phase One back (P45+). Is there any way to get the firmware updated short of sending the cameras back to Hasselblad? I live in Orange County, Ca.
I might add that it is a privilege to be a new member of this community. You guys are terrific.
