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.

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 .

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.

Re: regarding the 'data security' thread recently
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. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

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