you did ask ps2 connection to i2c in i2ctool thread, guessing it relates to this thread?

and http://www.nxp.com/documents/applica...te/AN10207.pdf

But i think "easiest" way is to use small microcontroller as I2C slave, and to interface to the PS/2 keyboard - it makes PS/2 data available to be read by phone - If want to experiment, use e.g. Arduino. Connect it to the phone with MyHalf

5V can be made with step-up converter.

All these parts are available from various sources (MyHalfs maybe not so many places)
