Sony Ericsson, Nokia stumble: will they be eclipsed by new mobile stars?

(GOOG), IBM (IBM) and Intel (INTC) all turned in solid earnings performances this quarter, prompting optimism about the tech space. But there were some laggards, particularly among mobile phone makers.

Sony Ericsson said Friday it lost $245 million in the third quarter due to falling sales, but skittish investors were comforted by news that the joint venture between Ericsson and Sony (SNE) had secured fresh financing from external investors. Meanwhile, Nokia (NOK), the world's largest cellphone maker, shuffled its management team, one day after reporting a whopping $836 million loss thanks to a steep decline in its smartphone market share.
