They are completely different operating systems. There is a lot of backend security in BB that iOS doesn't have. Sure, both have a grid of icons. BB has true multitasking with a tile/window interface. Blackberry messanger's newest version looks promising. There is a lot more, but simply reading about BB10 would tell you what you want to know. They way you worded your question makes it sound more like you are trolling than actually wanting answers.
