Life / is there wireless internet in poland [19]

I will be traveling to Poland in about a year from now and will be in major cities, and some very small cities. I was wondering is there any service providers that offers National Broadband Wireless, for example I could be anywhere in Poland (major cities, or out in the countryside) and still get wireless internet access. In the United States Verizon Wireless offers this sort of service (see b2b.vzw.com/broadband/coveragearea.html).

Thanks for your help in advance,

Keith
