Description
Currently the mobile app fails to use built-in SIM reader of my Sony Ericsson K200i:
DMM INFO subscriber.c:596 Requesting SIM file 0x2fe2 DSIM INFO sim.c:223 got new job: SIM_JOB_READ_BINARY (handle=00000004) DSIM INFO sim.c:712 go MF DSIM INFO sim.c:256 SELECT (file=0x3f00) DSIM INFO sim.c:181 sending APDU (class 0xa0, ins 0xa4) DSIM INFO sim.c:200 Using built-in SIM reader DSIM INFO sim.c:901 received APDU (len=0 sw1=0x00 sw2=0x00) DSIM INFO sim.c:979 command failed DSIM INFO sim.c:147 sending result to callback function (type=1)
This is what the firmware log looks like:

Note the key=20 pressed/released, I wasn't actually pressing anything.

This patch makes the SIM reader work:

I don't see key=20 pressed/released, and mobile can attach now, but I am not 100% sure if this is correct.
