If you happen to be using a HTC S740/743 (a.k.a. the Rose) and often wished you could run custom ROMs, today may be yourr lucky day.
XDA Member jockyw2001 has posted a HardSPL kit for the S740/743. The HardSPL basically opens up the phone to allow for the flashing of ROMs.
Presently, there's only one cooked ROM being circulated over at XDA for the HTC Rose and it may take time before the chef's start adding this Windows Phone to the menu.
