I'm fully aware of what the reviewer said. Whether it can download the map or not is not important and that don't account for the phone is whether a dedicated GPS or A-GPS.
The major factor here is a true GPS unit can log-on into your location as long as your can receive a clear signal from satellite, while AGPS will only able to do that thru. network mask. Due to it lacks of GPS hardware, it needs the network mask to process the satellite data and relay it back to the handset. In actual fact, i would consider it as approximation not log-on. (This software trick can be employ in other normal phone as well, not only C905)
Due to this, when your are oversea, your normal local sim card is not going to work unless you enable roaming and guess what is the cost of using roaming? What if when you are in the jungle for tracking? You loose the phone signal, you loose the AGPS.
unfortunately, you're still wrong.The major factor here is a true GPS unit can log-on into your location as long as your can receive a clear signal from satellite, while AGPS will only able to do that thru. network mask.

gps is gps, no tricks and cons. it'll work as it is, and will not need network access to get it work.
take an example, N95 can lock the position without any network access. the problem with phone GPS device is, they're not as accurate as dedicated gps device, and they take a long time for the initial locking, hence the need of Assisted-GPS, which need the help of GPRS for more information on satelite locking.
you can bring N95 for jungle tracking, no problem, just that it may have a hard time locking the satelite signal due to many trees blocking the sky.
