Hi guys .. newbie here .. i checked around and there is no newbie guide .. can some1 guide me to any good site to learn more about how GPS works in handphones ? Few things i want to know if u guys dun mind answering

1) Is it really accurate like those GPS navigator tat cos like 1k =.=
2) What is garmin XT or something like tat ? software or hardware ? need to pay ?
3) To use GPS in handphone .. do we need 3G connection ? Only MAXIS has 3g connection right ? And it's DAMN EXPENSIVE isn't it ? I asked before and i remember it was like 1c per kb or something .. then 1mb oredi 10bux ?!
4) and by GPS we all mean GPS navigator right ? as in if put in car .. it will move along with the map ?
