HTC has posted an info page for the upcoming T-Mobile version of the HD2 Windows Phone.  Aside from giving us our first look at the T-Mobile branded handset, it also reveals updated memory capacities beyond those of the non-U.S. versions of the HD2.

The RAM, system memory, and the flash ROM, file storage, have each received a capacity boost.  The RAM has been increased from 448MB to 576MB.  More interestingly, the ROM has been doubled to 1GB.

Why make these changes?  Most likely to accommodate the version of Windows Mobile 7 expected to be made available for the T-Mobile HD2 later this year.

In addition to its internal memory, the T-Mobile HD2 will also ship with a 16GB microSDHC flash memory card.
