GPS Cell Phone in Soda Can Form
Myko writes "PhoneScoop.com reports that Coca Cola has unleashed a new GPS enabled cell phone for a new promo. Apparently the user will push one button which will auto dial a Coke rep that will tell them they won an SUV. They'll then press and enable the GPS and the prize squad will drive to their location with the prize. So the big question is, will the phone give off any residual waves that will allow custom made detection equipment to find the right 12 pack, similar to the tilt and win iTunes trick? :)" We mentioned this last year, but it wasn't clear how the GPS-in-a-can trick was going to work.
On a side note, I went to school with a kid who won a Jeep in the Pepsi contest where each cap had a word and you had to make phrases. The phrase was like 'DO IT' or something. The Jeep had a ton of pepsi stickers all over it and the contract he signed required that he could not sell it or remove any of the stickers for one year. Of course he had to pay the tax on the $20,000 vehicle before they would hand it over. Still better than a kick in the pants, but it's amazing the hoops they make you jump through.

Still, the phone inside will be conductive, and in fact have an antenna of some sort to transmit the signal. A basic metal detector should be able to distinguish between an empty aluminum can and one containing a gps phone because of the differrence in inductance. Waiving around a beach-sized metal detector might not be such a good idea but it's not too hard to build your own hand-held unit.
Unfortunately this approach would require you to pretty much scan an entire display up close. Anyone with more knowledge of gps and cell phones have an idea of how to detect the components even when they're powered down?

It's a complete misnomer that the phone companies have been spewing the past year or so. It's not GPS but rather triangulation of the phone from the cell towers. It's GPS-like in that it can tell you about where you are but it's NOT GPS. GPS requires line of sight to several of the 14 GPS satellites which you wouldn't get inside a building or even in a metropolitan area with high-rise buildings all around.
Looking at the FCC docs, and this one in particular. The is a photo of the bottom of the can. On the bottom is a label, on this is text that says "Made in Finland". What the betting that the device has been made by Nokia?
If it's like my cell phone, it's a crippled form of GPS. The phone can receive signals from the GPS constellation but it doesn't have the electronics required to decode and process them. Instead, the GPS data is relayed to the cellular company's cell site, which has the equipment needed to calculate your position.
