Siri, tell me when iOS 5 is available. Nothing? Fine. Bash, you do it.

ios5_notify.sh

#!/bin/bash
while :
do
  echo "Checking for iOS 5: `date`"
  result=`curl -s -L http://phobos.apple.com/version | grep Restore | grep iPhone | grep 5.0`
  if [ -z "$result" ]; then
    echo "Nothing yet..."
  else
    say "I O S 5 IS NOW AVAILABLE. GO GET YOUR DOWNLOAD ON, KID"
  fi
  sleep 30
done

This is awesome! Just copied this script and I have it running now!
