I understand that the Droid is capable of Wi-Fi use in order to speed up the internet access or use it in the absence of a verizon signal. My question is, how is it used? In other words, when I connect to a network on my Droid, which applications utilize the network and what happens to the Verizon signals? Say I'm connected, does ALL of my internet data go through the network and NONE through Verizon? Does it do a combination of the two? Does the youtube app, browser app, gmail app, and all other internet apps all automatically make use of the network connection? Also, when connected to wi-fi, I assume my transactions are only as secure as the network I'm connected to. Is there any reason to even use wi-fi other than to speed up some youtube videos? Thanks.
