It can't use the towers without service. However those are only needed for the "assisted" feature, which reduces the time it takes to get a GPS lock during a cold startup.

I know it is a real GPS unit. But since it gives a relatively good position very fast and indoors it must use something else than GPS since GPS is not that fast. So it can use WiFi or the cellular towers. Are you relly sure you need a simcard to us the cellular triangulation?
But my point was that even if you do not want to pay for 3G data it is worth to get the 3G model anyway.
