Dream PDA addendum
Posts: n/a For the GPS wish, it would need to be independent of tower communication, so if I venture away from service, I still have full GPS capability. For IP, GPRS or newer with the possible option of WiFi, so if I have problems with tower access, I can try and use WiFi as my backup. Thanks again. Scott  Responses to "Dream PDA addendum"

Which is fine when away from tall buildings. Unfortunately, in cities where the buildings are mostly 10 stories or taller, the GPS signals are blocked. -- John Richards

Ah, but many phones with GPS receivers require a connection to the network to do the processing of the signals and calculate the location.

Ah, that's interesting. And, dare I say it, a bit bloody useless if you're out of range of the cellular signal. Hmm. I'm going to look into this a bit more. Thanks for the information. mark --
