Actually I have a skype application installed on my phone, so once I found a place with free wi-fi access I can make a call to Russia without problems. Or as another option I can make skype calls via 3G network if I get an Internet access plan for a local cellular network.

Did you mean that there are places in US where there is no cellular network signal but there is wi-fi? I have never met such type of coverage in Russia, we have almost total coverage by cellular networks while we have wi-fi points mostly in cafes, shopping centers, airports and other places like that but not an area fully covered with wi-fi.
