Apple's Siri Matches Wits with Zooey Deschanel and Samuel L. Jackson as T-Mobile Ditches the Pink [Updated]

Apple's all-knowing Siri declines to verbally mangle "Zooey" (it's pronounced "Zoe") in a co-branded (above, for AT&T) new campaign for the iPhone 4S personal assistant, who Ms. Deschanel calls on to cater to her quirky whims. The commercial follows the actress/singer's previous "Fabric of our lives" promo for cotton, and her makeup campaigns for Rimmel London.

AT&T's celeb spot is launching head-to-head with another quirky brunette's mobile pitch: the new campaign for T-Mobile featuring Canadian model Carly Foulkes, who ditches her good girl in pink guise for a Ducati-driving "No More Mr. Nice Girl" black leather-clad babe in its new campaign — check it out below — while Siri also lends a hand to another celeb in a second new spot, featuring actor Samuel L. Jackson.

AT&T also pairs Siri with another celeb in need in its new commercial featuring Jackson prepare gazpacho for "date night" with Siri's help. (Update: Verizon Wireless is also running this spot with its logo, so Apple's new celeb spots aren't exclusive to AT&T.)

And below, watch how T-Mobile's new Alter Ego campaign was teased on YouTube and Facebook, where brand fans were invited to go back and check out the first "lady in pink" commercial starring Foulkes in 2010, for the MyTouch 4G:
