Wrong. Memory cards can be made 100% safe and secure in a BlackBerry. Just simply treat the card as a memory upgrade module instead ("File Free: 500,000,000+") and use the existing memory "Content Protection" system found in Options->Security. Makes it impossible to steal data.

A specific memory card would be signed to work only with that particular BlackBerry, and be uncrackable even by CIA, just like when CIA removed the built-in flash chips to try to crack the memory. The removable flash card would apply identical encryption, it'd just be easier to remove -- but equally hard to crack.

In addition, SIM-card style memory called MicroSD are "semi-permanently" affixed behind the battery (like SIM card), making losing the card a total non-issue. For more information, read my previous article above.

Wrong. A total nonissue. Read the above.

Repeat after me....
"MEMORY UPGRADE MODULE", not "FLASH MEDIA"
"MEMORY UPGRADE MODULE", not "FLASH MEDIA"
"MEMORY UPGRADE MODULE", not "FLASH MEDIA"


100% secure, 100% encrypted, 100% safe in a BlackBerry, and since it's put semipermanently inside the BlackBerry just like a SIM card, loss is a nonissue.

The "encrypted data algorithm" is already on your BlackBerry. Just go to Options->Security->Content Protection and turn it on. Your builtin flash memory is now encrypted. Same algorithm could easily be applied to a removable flash memory, which would automatically force it to only function in that particular BlackBerry. Nothing new really needs to be invented.

The main complexity going forward is simply red tape (inertia of introduction to a security-adverse market and squeamish executives), addition of a SIM-like memory card slot (ie MicroSD), and upgraded software to support the extended flash memory (which could potentially be made completely invisible to the applications).
