No, Lattelekom definitely has not joined the Boingo WiFi hotspot subscription network. It has offered a subscription to its own 130 location network in Latvia, including Double Coffee ( a kind of Latvian Starbucks), various restaurants and hotels and Statoil gas stations around the country. For LVL 2.95 per month you get to log on anywhere for LVL 0.005 (that's half a santim) a minute. For LVL 10.95 a month you get unlimited access, sometimes at 2 Mpbs or even 4 Mbps, depending on what the hotspot has to offer.
Right now, at home, I pay around LVL 15 per month for 512 Kbps, which barely ranks as broadband in Scandinavia. So I am expecting a rise in speed or a cut in price for DSL, otherwise I move to Double Coffee down the street :).
Meanwhile, there are places like centrally-located Hotel Reval Latvia and the nearby Ridzene that offer WiFi as an amenity, for the price of a cup of coffee or a drink at the bar. For guests, it is free. This draws the WiFi battlelines in Riga. Then again, why not wardrive and see where else one can freeload? :)
