An anonymous reader writes "Since Edward Snowden started making NSA files public last year, GSMK has seen a jump in sales. There are more than 100,000 CryptoPhones in use today. How secure they really are will be determined in the future. But I'm sure that some government agencies, not just in the U.S., are very interested in getting a list of users." For the price the company's charging for a modified Galaxy S3, it had better be as secure as they claim; otherwise, the free and open source RedPhone from Moxie Marlinspike's Whisper Systems seems like something to think about first.
