In response to Apple thwarting attempts at unlocking the iPhone, Nokia has launched an “Open To Anything” ad campaign which flaunts the friendlier attitude they have towards developers who have created third-party apps for the Symbian Series 60-Based N-Series handhelds. With this campaign launching only weeks after the Apple whipped the hours of work by many developers by making their apps unusable with the 1.1.1 firmware upgrade to the iPhone, it’s clear who this ad is targeted towards. This is bound to get dirty.
