Basic steps:
- Set up a Gmail filter to add a label to a pool block notification email
- Set your Android phone to make that special sound when that label comes in (not sure if iPhones can do this or not)

If you need more detail on this see here . . . . I didn't want to fill this thread with slightly off topic details.

P.S. you can also use this to set up a RED ALERT!!!! sound when you get an idle miner notification.
