Nope, integrated wi-fi means that it's built in....obviously. Anyways, it does mean that you can connect and surf the web when you are within a wireless hotspot.

And just like an iPhone, you can either use the wireless hotspot, or connect through EDGE.

I have a Cingular 8125 running Windows Mobile 5, and loving it. I don't see how you can go wrong with the T-Mobile Wing running WM6.

Good Luck
