Nokia is suing Apple for infringements on their GSM, UMTS and wireless LAN patents. $US200 million. Update.
The ten patents in suit relate to technologies fundamental to making devices which are compatible with one or more of the GSM, UMTS (3G WCDMA) and wireless LAN standards. The patents cover wireless data, speech coding, security and encryption and are infringed by all Apple iPhone models shipped since the iPhone was introduced in 2007.
Apparently, the wireless technologies in question mean that the iPod touch is off the hook.
UPDATE: Gene Munster estimates that the patents add up to $US6-$US12 per phone, meaning that Apple would owe Nokia roughly $US200-$US400 million based upon the estimated 34 million iPhones sold to date. [BusinessWeek]
