Rockstar have today announced the development of Chinatown Wars and Beaterator for Apple's iPhone and iPod Touch platforms. Both titles are expected to be released this spring for the PlayStation Portable device as well, with Chinatown Wars currently available on the Nintendo DS.

Both titles are being developed by Rockstar's Leeds division, who previously worked on mobile titles such as Grand Theft Auto: Liberty City Stories, and Grand Theft Auto: Vice City Stories, and recently picked up the 2009 Develop Award for Best Handheld Game Studio.

We'll be bringing you our findings on the PSP versions of both Chinatown Wars and Beaterator later in the week.
