Travel Technology - DEN Wifi

I am not too sure if this is the right forum, so pardon me if it is not. I have done a search, but not found anything. I am connecting in DEN for four hours on UA, and will have my laptop with me. Where is the best place to get wifi? I don't have T Mobile, but would be willing to buy a day pass.

Thanks,
Ben

See section on Internet Access on DIA's website below: http://www.flydenver.com/guide/services.asp

RCC may use T-Mobile. I don't remember for certain.

RCC has Tmobile; rest of the airport, iirc, has ATT

Watch at Starbucks for Tmobile free day brochues. I've also seen folks selling them on eBay.
