Nokia chief Olli-Pekka Kallasvuo said his company has "over invested" in R&D in the U.S. market, and instead will pursue an incremental strategy of expanding its portfolio in the market rather than looking for the silver bullet in the mid-priced handset range. The U.S. market represents less than 10 percent of Nokia’s annual global shipments, and Nokia never gained a foothold in the U.S. CDMA market, which it bowed out of earlier this year. Kallusvuo said there was "no magic bullet" that would help Nokia gain more market share, only that the task required "hard work and more hard work." Of the four slim phones the world’s largest handset maker introduced yesterday, only one might work in the U.S. on T-Mobile’s network. The Nokia 6086 is a mass-market UMA phone that supports quad-band GSM, but it looks like T-Mobile will have to heavily subsidize it to make it appeal to the mass market.

Before I go in to rant mode, I don’t think the problem with Nokia’s sales in the US is a technology issue. It’s a carrier issue. People think the only cell phones they can use are from their carriers. This kills choice, which kills sales.
