Well, the wait might be over, because it looks like the game has just arrived at iTunes. Unfortunately, the game might not yet be available across all stores right now, but it should be soon. Meanwhile, it is believed that the Android version of the game will also arrive in the Google Play store promptly. According to Rockstar Games selected Windows Phone and Amazon Kindle devices will get the game in the near future as well.
The iOS version of Grand Theft Auto: San Andreas will feature remastered graphics and will include dynamic and detailed shadows (available only on iPhone 5 and above), greater draw distance, enhanced colors and models, allegedly making it the best looking version of the game for any platform. Apart from the tweaked graphics, the game will feature several different input methods, new touch controls that will become visible only when you need them, and reworked checkpoint system. GTA: SA will also support all Made-for-iOS physical controllers and just like in its PC sibling, the iOS version of the game will allow its users to create a custom radio and listen to it while playing the game.
