New Nokia Phone Sandboxes and Clones SIM?

[hk39v7]

I just read about a modded Nokia 3310, that sandboxes and clones the SIM, with a different IMSI every time, to prevent interception; but keeps your phone number, so you can still receive incomming calls. This phone is available worldwide, as it is not an IMEI changing phone, which are illegal in western markets, because of antiquated laws, that were originally designed to prevent airtime theft. The telecom equipment and administrative environment in the east is so new, that countries like India and China do not have either legacy environment; so you experience a less restrictive telecom environment there.

Anyway, here's the boiler plate text about this feature:

----------------------------------------------------------------------------------------------------------------------

2 -IMSI Change which is transforming the phone in a real sophisticated counterintelligence weapon. IMSI Change function does not require any Internet connection, third party servers or monthly subscription. This special function runs locally on the phone (Sandbox partition), being a unique function which no other phones offer at this time.

IMSI Change function allow user to change IMSI value (SIM registration number stored on the SIM card), by keeping the same phone number (MSISDN).

How does it work?

The phone will clone any SIM card inserted (please use only MNO SIM Cards) by using a Sandbox located app: IMSI Virtual Engine. Once cloned, the real SIM will be quarantined, being used instead a virtual SIM card which can change its IMSI by by generating valid IMSIs. Please note that abusing this function can generate SIM network rejection (network dependent). Use it carefully. IMSI Change does not work automatically, as IMEI change works. The user should launch IMSI Change every time when a new IMSI is needed, generating a new virtual IMSI and then exiting the application. The new generated IMSI will be used only for the next outgoing or incoming call. After that, the phone will return to original IMSI. If a new IMSI will be needed, the whole process should be repeated. Please note that MSISDN (the phone number) will not change when using IMSI change function. IMSI change function will transform your Phone in one of most powerful communications weapon: you will literally have a new SIM (IMSI) for every single phone call. Use it with precautions.

Gee, I'd sure like to teach my Samsung Galaxy this trick. Are there any apps that will do this, since this is a brand new technique without any curent legal restrictions?
