It probably still uses A-GPS cellular tower.
Try getting a lock outside the US in a country like Equador. See if it still gets 15 second lock and I will be surprise that it locks faster than a SIRF III gps chipset.
The iPad gets 10-15 seconds lock in the US. I don't have any data plan on the Ipad and it does the same 10-15 second lock.
