The not-so-good news of it all is that while the Lumia 620 is making an appearance in the U.S. market, it's not with a major carrier. The Lumia 620 is being offered by the relatively new wireless carrier Aio Wireless.
Unfortunately, for the time being, the Aio Wireless service is limited to the Tampa, Orlando, and Houston areas. The company does have hopes to expand nationwide within the next year. This may not be good news for those of us on other carriers or that live outside these limited markets. But it's a start.
If you happen to be in one of the three Aio Wireless markets and are looking to make a switch, the Lumia 620 is running $179.99 (no annual contracts) with rate plans starting at $55.00 a month. The Lumia 620 is being offered with the cyan shell but customers can exchange the cyan shell for violet, yellow or green shells at no cost at Aio Wireless retail stores.
