This looks pretty interesting. The Beta launched today (for Android - claims it does no tracking of your cell phone data/location), and I am already tempted. If anyone is trying this out, please let us know the pros/cons of this product?
While it's kinda cool (but not really anything special, likely just reprovisions the software UICC profile) - it fails to mention that the device IMEI still remains the same (as per regulations), so it can still easily be tracked (IMSI doesn't technically need to be unique/single use, but the IMEI must)
IIRC changing the IMEI in the U.S. is legal. It may go against standards or something, but that's not a crime (though it would be an excuse for a carrier to kick you off their network, should they find out).
I would be shocked if there were real consequences for IMEI spoofing in the U.S. absent any crime (like stealing lots of phones and changing the IMEIs).
