US website Pocketnow reports that T-Mobile USA has cancelled plans to launch Nokia’s C5-03 smartphone, which it was set to offer as the Nuron 2, without specifying the reason for its decision. The news is significant in that it comes less than one week after reports that the launch of a flagship smartphone from Nokia for AT&T had also been shelved, although in this case it was suggested that Nokia was behind the decision, following a lack of commitment from the operator. According to Pocketnow the original Nuron (a rebadged Nokia 5230) sold “well.” The C5-03 (pictured), which is already available in other markets, is largely unremarkable: it uses the aging S60 5th Edition rather than the latest Symbian^3, and has a 3.2 inch touchscreen.

Nokia is undoubtedly seeing its position in North America go from bad to worse, especially in the lucrative smartphone sector. According to the company’s Q3 2010 results, it shipped just 3.2 million devices in North America during the three months, representing less than 3 percent of its global shipments. The region is also its smallest by far: next up is Latin America, where Nokia sold 11.6 million units in the quarter, more than three times its North American total. AT&T’s website currently does not list any Symbian OS devices from Nokia, while T-Mobile USA offers one – the first generation Nuron. Nokia also has a limited exposure to the CDMA market.
