I installed 4 apps and 3 games on my iphone and when I connected to my macbook itune shows 190mb other used. I was ok with it since 200mb is not a whole lot. Then tonight when I sync my iphone it shows 215mb other used and I done nothing, but watch a couple video on youtube. Does Iphone store history, cache or something cuz if they keep piling on every time I watch a video or download something then i'm gonna run out of space fast. So what is up with this and is there any solutions to this?
