Internet access via wifi shield and cell phone hotspot - anyone done it?

Just wondering. I've asked quite a few questions on Arduino official wifi shield with no answers. Maybe there has not been a user base for this hardware yet since it just came out not long ago?

I wanted to access internet via cell phone wifi tethering. Here is some instruction I found but I don't have tethering turned on yet with my phone. Just wondering if anyone tried it.

I have not got the hotspot turned on yet. AT&T charges me a hefty fee if I want to tether a wifi device on my phone. So what does that option do? Thanks.
