I am a fan of Doodle Jump And I wanted to buy 321 Jump! The problem is that I have a 1st gen iPod Touch and it only works for iPhone and iPod Touch 2nd gen. Why is that? I would really like to buy this game. Thanks!
probably just a developer fluke. He forgot to check a box allowing your device to play it. Send the developer an e-mail, he should have it fixed soon.
