With the Engadget article today that says the iPhone will more than likely have an A-GPS, I did a couple searches on Google to figure out what A-GPS meant. Nothing directly answered my question, so I’m hoping some of you can shed some light. 1) Is A-GPS a true GPS? 2) What is better for a phone, what I read made it seem like A-GPS was better, so why doesn’t everything use A-GPS, what’s the drawback? 3) Is there anything about having a standalone GPS that’s better than an A-GPS? 4) Will we need to be connected to the cellular network to use A-GPS, or can an A-GPS connect to the satellites directly if we are not within a cellular network? Basically, if we temporally loose our signal, does the A-GPS cut out as well? 5) Does it being A-GPS and not a standalone GPS increase the likelyhood that we could be charged monthly to use/unlock the GPS since it could be dependent on the cellular network? Thanks for any help.
