Revealing mistake: When Jensen is investigating the missing 4 million dollars from the account, we see the screen on his laptop. Among other things, it shows a picture of Fadhil's passport, which looks like it has a watermark on it, readable as http://slawek.com. Indeed, going to http://www.worldpassports.org/americas/pages/bolivia.htm you will find the passport pictured there. (01:01:35)
Continuity mistake: When Jake disguises himself as a messenger and enters a building intending to hack into a computer, he shows up at the ground floor lobby with his bicycle. Behind him, an Asian lady also turns from the lobby and walks past him. In another shot, the very same lady is seen entering the building from another entrance.
Jensen: Did you know that cats can make one thousand different sounds and dogs can only make ten? Cats, man. Not to be trusted.
