This has prob been asked many times. Im just curious to why the Iphone gets instant push notifications? Facebook,twitter,instagram are usually instant once they get a update/tweet,etc.. Like why is the facebook app only allow 10min intervals? Even friendcasters push notification is slowly sucking. and my twitter app is 1 min intervals but eats battery faster with it that low. Gmail is the only thing i know thats instant. Im just curious to if its the OS or apps?
