No it depends on the phone and the type of gps that it uses. The Touch Pro has AGPS wich is assisted gps that uses the internet to get a quicker fix along with using cell phone triangulation to help with poor reception areas. However the gps chip in the phone will get a lock without a data connection and without the phone radio being on bc it has a regular gps as well.
There are some things that you can do to help if you need locks without the phone radio being on. You can turn off the AGPS and just use GPS its a setting in the registry that you can disable and also a setting in EPST that you can change to turn off AGPS. Your best bet to get faster locks with regular GPS is to use Quick GPS to download the sat info and store it on the phone this will stay valid for 7 days and won't go out to the internet to lookup the gps over the net to get a quick lock. Without that it can take up to 10 min or so to get a lock without help or a clear veiw of the sky. Thats just the nature of regular gps and a cold start.
