Wi-Fi and Tethering

Hello Crackberry nation! I am switching from VZW to ATT at the end of this month and am going to be getting the Bold. With its Wi-Fi capabilities I know that I will have Wi-Fi speeds on my phone, but will that be applicable if I tether to my laptop? (ie will I have Wi-Fi speed on my computer using my phone?) Or am I going to be limited to 3G/EDGE speeds? I have a Starbucks Hotspot across the street from me so I'd prefer to just pay the 30 bucks extra for the tethering capabilities instead of 60 bucks for a laptop connect card. Any info is much appreciated. Thanks!

What are the instructions to tether your blackberry? I was looking into walkinghotspot but need an equivalent solution for the blackberry platform.
