So, I'd been waiting for the Samsung Galaxy S wifi 5.0 to be release here in the U.S. It never was. And I'm curious as to whether I could get an android phone and use it the same way without having any sort of plan with a phone carrier. My main concern is whether I'd be able to access the android market OK over Wi-Fi. I understand that some GPS apps need a constant connection to download maps as you're going along, but I guess some of them actually allow you to download it before hand.
