"Apparently there is a quick, simple, and undetectable way to grab all of your cellphone data. CNet reports on the Cellular Seizure Investigation (CSI) Stick, developed for law enforcement but available to the public, which 'connects to the data/charging port and will seamlessly grab e-mails, instant messages, dialed numbers, phone books and anything else that is stored in memory. It will even retrieve deleted files that have not been overwritten. And there is no trace whatsoever that the information has been compromised, nor any risk of corruption. This may be especially troublesome for corporate employees and those that work for government agencies.' I use mobile knox, a secure storage application, for my important data, but I would be very upset if somebody grabbed my telephone list, SMS, or anything else from my locked phone."
