I find it interesting you remark the delay has not caused problems with gps accuracy. No, I am not seeing a delay. I consistently get a 1 second correction age. You have a phone you purchased for data communication. Is it any different than a typical phone we all use for voice communication and/or does it matter? What I mean by that is do you need a signal 100% of the time to get quality gps fixes via cell internet like you need when talking on the phone? OR, is the cell internet data stream able to be collected in broken segments and assembled to create accurate fixes? If so, then it is much easier to understand how a questionable coverage area my be able to provide the necessary signal to create good gps fixes. What might the maximum time be to maintain accurate fixes? I am using the HTC 6800. I have seen the signal strength get down to 2 bars, but the data stream continued. I don't have the knowledge to answer the rest of your questions.
