There's other issues as well, like you don't need the tmp file. Here is what I have at the moment:

#!/bin/sh
VALID_IMSI=
SEND_TEXT_INTERVAL=120.0
HOME_PHONE=
TIME_WAIT_TO_CALL=60
ALERT_CODE=""
imsiNum=`dbus-send --system --type=method_call --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM Phone.Sim.get_imsi | grep string | cut -f 2 -d '"'`
echo $imsiNum
if [ $imsiNum -ne $VALID_IMSI ]; then
python /usr/sbin/sms.py --sendinfo $HOME_PHONE $SEND_TEXT_INTERVAL $imsiNum $ALERT_CODE
python /usr/sbin/sms.py --listen 0 $SEND_TEXT_INTERVAL $imsiNum $ALERT_CODE &
sleep $TIME_WAIT_TO_CALL
run-standalone.sh dbus-send --system --type=method_call --print-reply --dest=com.nokia.csd.Call /com/nokia/csd/call com.nokia.csd.Call.CreateWith string:"$HOME_PHONE" uint32:0
else
python /usr/sbin/sms.py --listen 0 $SEND_TEXT_INTERVAL $imsiNum $ALERT_CODE &
fi


Notice that you don't need to write/read a tmpfile, you can just use a backtick. But for some really annoying reason it still isn't working,

p.s You didn't just copy and paste my tar command? I think you might have picked up sms-manager with the wildcard if you did.
