Question guys,

I'm planning to get a PDA phone with GPS, either HTC or Samsung, i heard from somebody that those GPS that is built in, will activate 3G or HSPDA, means....kena charge for the data. But after browsing a lots of thread here, i just can't be sure, i read GPS...no charge...AGPS charge. So...which one is which one ?
Will HTC or Samsung phone GPS get charges for data if use GPS ?
