WSJ.com: Symbian Gets Boost, But More Politics, From Siemens Deal "Symbian, a consortium of mobile phone companies that is developing operating software for wireless devices, received a boost Tuesday when Siemens AG (SI) said it would pay EUR22.8 million for a 5% stake in the group... The deal means that four of the world's top five mobile handset makers have stakes in Symbian. The group is increasingly seen competing directly with Microsoft Corp.
