I like the idea but would be concerned that an annoying noise, even intermittent, would result in the device being thrown away (as defective) or destroyed (as annoying and attention drawing). Neither of which get me my device back.
Something similiar was recently mentioned on Jason Langridge's weblog.

Looks like the comments on the linked article also include another:

Both of these are trained on your SIM card, so that if a different SIM is loaded it will automatically send an SMS to a number you select. Then you'll have the phone number of whoever stole your device and a lot better chance of the police retrieving it for you.
Now to have both features, data deleting and SMS notice with optional device locking... that would be awesome.
