MTV Networks' Nickelodeon is making your iPhone more appealing to your kids with the introduction of apps featuring content from three of its hit series: SpongeBob SquarePants, Dora the Explorer and iCarly.

Although the network posted a "mini-application," the SpongeBob Tickler on the App Store in late January, Nickelodeon considers these new applications as its first official foray onto the iPhone.

First up is SpongBob SquarePants Atlantis Treasures, which launched on Thursday. The others will roll out throughout the year, starting with a Dora app launching in March.

Details on all of the new Nick offerings are after the jump.

* The Dora the Explorer application will challenge kids to match shapes, count numbers and practice the alphabet in touch-and-shake-oriented game play.
