Wifi enables you to pick up your home internet and have your BlackBerry browser to run faster. It's your choice to use the option but it does boost your browser speed.

Wifi is a nice option to have as it allows faster data transfer. And yeah, you'd need the 8530, Storm 2, of as yet released Tour 2, for the Wifi functionality.
If you have VZW and a Wi-Fi capable device, you can connect to the Wi-Fi for data and be able to talk on the phone at the same time while you browse the Web.
For some reason my house is a dead spot, barely get 3G every now and then. I have to use the WiFi signal from my router. I dont mind though...WiFi flies compared to 3G.
Thank You all for the input! Just to clarify... I am aware that my 8330 does not have the WiFi option. We are looking to upgrade and trying to decide if we want to go with the Curve 8530 or the Tour and that was one major difference I had seen between the two.
Again, Thank You all!
