maybe he didn't work in the iphone apps division? iphone app development maybe - not everything revolves around the iphone dude. and btw.. i'm 35.. a very old man - in most TA's users point of view. but i've been developing in the mobile space for 15+ years.. even before most here were born.
All we need is proof of one thing he's done, it doesn't even have to be a game. I've never seen a dev asking for staff/beta testers who couldn't at the very least provide a website or info on a previous game.
Don't you think that if he indeed worked at Gameloft for four whole years that he would have proof? And his actions are very odd and point to the obvious conclusion.
