double twist with 4.0 (itunes to Evo 4g LTE)

[HnLA]

I have been trying to get double twist to work, to transfer my music on itunes to my new HTC Evo 4g LTE. As with everything I have tried to sync to this phone it just does not work. Double twist says I need to have USB mass storage mode versus USB MTP mode. I have never heard to these and never had a problem with USB connections until I got the Evo.

The instuctions show previous versions of android, so cannot follow instuctions on my computer.
Anyone know of a good way to get itunes music to Evo 4g LTE? Thanks
