Like I said b4, the iOS is so simple to use that my 5yrs old cousin can use it without running into much problems, although he doesn't do much on it when he comes over to my house. also, I jailbroke mine so the customization is well up there.
Android rapes iOS in every aspect. It's being developed faster, has more features, better selection of free apps imo, just works the way you want it to work and is by far the more customizable OS. You can download like a million different version of it with a million different kernels.
