Not by default!! People that travel between North America and Europe 
often maintain two (or more!!) SIMs to take advantage of cheaper calling 
in different {countries,continents} by having a local number.

For bonus marks, have it send gps coordinates charged against the

But for users like me with multiple valid SIM cards, I think being able 
to run a script/app on the phone that says "this SIM is valid, don't do 
a wipe" would be necessary -- keep a 'catalog' of allowed SIM's.

If an unknown SIM is inserted, send an Email to some central location 
with the phone number of the SIM that IS inserted, so you now have the 
phone number for which to send the 'wipe' SMS message.

Just my $0.02.

LOL.

This was my first reaction, too, and was just about to post to the  
list and ask the same question when I realised the answer.

The new phonenumber doesn't matter, because it'll wipe the phone when  
the thief's friend sends them a text message.

Having said that, why wait for an incoming text?
Why not just have the phone wipe itself when the SIM card changes?
You just need to store the original SIM ID in flash memory and check  
against it at start-up. The software can add an additional function  
for "change SIM card" which will allow the user to do so safely ("add  
SIM card" is probably better - if it allows the phone to check  
against a whitelist of multiple SIM cards then users can swap between  
two tariffs easily, without having to worry about activating this  
function EVERY time they do so).

The erasing of personal data can be done silently without alerting  
the user (thief), and doesn't need to interfere with an additional  
feature of "phoning home" its details in the event of theft .

If phone will wipe itself if no authorized SIM is present (and program
starts as daemon, of course), than it won't be real security hole.

... by the way : to what phonenumber will you send a sms when the thief 
has replaced the sim card?


you could also test, if there is the selected SIM card in the phone.
and if not, you send the GPS-Data of the phone every 10 minutes per sms  
to a pre given phonenumber.
so you could find your phone. (and you have the phonenumber of the thief 
:) )
If i think about it, we should just send every 30min. because it would 
be annoying to recive a sms every 10 min.



but all these things are just functional if you are the only one who 
have implimented that feature.
That's the bad side of the open source thing. If you put it in the 
general source tree, everyone
knows where he had to put his SIM card numbers, so the phone think 
everthing is allright.

but it will work for quite a while, because i don't think that so many 
street thiefs are receving this list.:)
And maybe it will take a long time until they realise why always the 
police stands in front of their door
when they had stolen a Freerunner. :)




i like the idea of the self sending GPS data. It costs the thief money, 
that we know where he is :) ... you could say, he paied for getting 
arrested :)

About data wipe:

I was thinking -- doesn't eny SIM card have some kind of ID number?
And if they do, do we have software way to obtain it?

Phone could wipe itself if another SIM card is inserted AND upon SMS message
receiving.


If you have several SIM cards, than we could create simple SIM card
whilelist.

I see that the 3G iPhone will now have a 'remote wipe' feature similar 
to what we've all been discussing.
