Don't know if others have discovered this already. Using COM3 (23053), if you touch and hold the SIP button in the soft key bar, it will bring up the good ole input mode selection menu so you can choose among the cooked in SIP options. I only include NullKB, HTC Full QWERTY, HTC Compact QWERTY and HTC Phone Keypad.

Note - if it doesn't pop up the selection menu, check the following key and make sure it's set to 1:

HKLM\Software\HTC\ezsip\EnableSipMenu=dword:1

Finally, I'm using version 1_5_32548_0 which (I believe) is from the Verizon HTC Touch Pro CDMA maintenance release. It works fine with 23047, 49, 52, 53 and 21815 (those are the 6.5 builds I've tried it with). At least one newer version had a nasty habit of recording five key presses for every tap on the compact QWERTY keyboard.
