Adding more fuel to the fire that a Lumia 900 is going international sooner than later, the phone is now listed on the site Obchod S Mobily found in the Czech Republic. While no date is given for release there is a price which amounts to be about $760--certainly not cheap, although who knows if that will be the final sale price or is just a placeholder. As the website Techin5 points out, some of the detailed Lumia 900 specs are a bit off but Obchod S Mobily are most likely not confusing it with the Lumia 800, as that phone already has a landing-page there. It's also worth noting that only an 8MP camera is listed and not the rumored (but unconfirmed) 12MP variant that some sites are reporting.
Regardless, between Carphone Warehouse, SG Best and now this Czech site, we're very confident that Nokia's flagship phone should be hitting other countries within the next few months. While Carphone Warehouse had a June date, it could be sooner than that and hopefully Nokia will reveal more at Mobile World Congress.
