A class action lawsuit was filed late Thursday by an XDA-Developers forum member over Samsung's allegedly intentional delays of Android 2.2 upgrades for the Vibrant. The complaint accuses both of violating the Uniform Deceptive Trade Practices Act for promising an update in the short term but delaying to the point where the Vibrant 4G would ship with the OS already onboard. The two companies hadn't lived up to promised fixes and was saving them for a new model, the new plaintiff said.
