Mobile games developer and publisher Gameloft says it has over 15 iPhone/iPod touch games in development.
The firm has previously developed games for Apple's scroll-wheel based iPods, including an adaptation of its TV tie-in game Lost.
"The iPhone gaming environment opens a new era in mobile gaming and is exactly what we've been waiting for," said Michel Guillemot, president of Gameloft.
"The Apple iPhone has changed the way consumers perceive and interact with their mobile phones, and the release of the SDK is a tremendous opportunity for Gameloft to apply its creative and innovative approach to mobile gaming.
"Due to our investment in creating one of the most advanced and creative development studios to date, we are ideally positioned today to seamlessly integrate new opportunities and quickly produce games that are as evolutionary as they are enjoyable."
