I don't actually know when it will be coming but I would imagine it will be a short while yet, as the american carriers like TM usually get new releases at least a month ahead (if not more) of most UK carriers, and as far as I am aware none of the US carriers have 4.1 for the standard 7100 as yet. Having said that you can load one of the American Carriers 4.1 (once they are available) onto a 7100v (my 7100v's 4.0 is not Vodafones version

), however before it will load you would need to scour this forum for info on how to load another carriers software (you will need to find and delete a file called vendor.xml off your PC).
