Part of the action is supposed to take place in Paris; At one point Jamie Sommer is driven away at the back of a truck; when the backdoor is closed, we can see the phone number of the "so-called electrician" painted on the truck; the phone number reads "55.50.XX.XX". An actual French phone number would have a 10-digit scheme with "0" as the first number. Although the phone number is written "the French way", the first three digits actually reads the conventional "555" used for American TV shows.
The iPhone is upside-down when the man was using it to talk to Jamie to negotiate the price of the "List" and Tom.
