TomTom to Add GPS to the iPhone?

Here's a fresh rumor for you.

Apparently, TomTom has developed an add-on GPS receiver for the Apple iPhone. The thing you see on the picture here is obviously the GPS module we're talking about, as on the phone's screen we clearly see GPS navigation prompts.

As you've probably heard, the upcoming iPhone SDK that should appear in February, is already available to some developers, not excluding TomTom, so, it is very possible that the manufacturer came up with this accessory as an alternative to the official GPS-enabled iPhone, which is still not ready.
