The latest issue of Japanese mag Famitsu reveals Square Enix's Chaos Rings, which is apparently a new Japanese RPG for the iPhone and iPod Touch. 1UP's translation indicates that Chaos Rings features art by Final Fantasy vet Yusuke Naora, and that the plot follows five teams of two, each of whom have their own storylines. Destiny and eternal life plot lines ensue.
The battle system is apparently built around solo and pair moves by the characters, the latter dealing greater damage and unlocking more combo skills. We're currently following up with Square Enix in North America and will update if it has any further information.
