So the iPhone seems like a pretty good business tool right? Wrong, at least that’s the case if you work in a business where you sling around code names or other secretive info in emails, text messages, or other text based communications.

So if you have hacked your iPhone and have access to the drive contents, feel free to go to /var/root/Library/Keyboard and take a peak at the contents of the dynamic-text.dat file. That’s right; it’s essentially all the words you have used that the dictionary, the one for auto-correction whiles you are typing, didn’t recognize.

So, what kinds of things get recognized by something like this? Passwords, usernames, secret product names, the list goes on, but lets just suffice it to say that maybe you might not want to use your iPhone for anything you don’t want made public. All that stuff, passwords, usernames, everything, its all stored in clear text, not encrypted or anything, so be cautious, surely someone will come up with a tool to encrypt this, delete it every so often, or just plain disable it, but until then, be careful.
