Unblock iPad/iPhone from connecting to Wi-Fi?

My brother blocked my iPad and iPhone from connecting to Wi-Fi, how do I unblock this?

Added (1). No he didn't turn Wi-Fi off, he just blocked me somehow. He didn't change the Wi-Fi password either. He somehow went into the router settings and blocked me, so how do I go into router settings and unblock me. I'm using iMac with an apple airport router.

My iPhone touch screen is not responding! IPhone 4S?

And now when everything's back together the screen has stopped responding to touch. The screen lights up and everything, but I can't touch anything at all. It won't respond. I restarted the whole phone, and also reset it. But it still won't respond to touch! Please help!

Is there an app that transfers drawings from one device to another?

I have an iPad and an iPhone and I was wondering if there was an app to transfer what you drew. For example: I draw a circle on my iPad, which in turn shows me drawing a circle on my iPhone.

Forgotten restrictions code?

Last year after Christmas my mom put a restrictions code on my iPod… And now she's forgotten it. She can't think of anything that she hasn't tried. But luckily, I'm getting an iPhone soon. Can I transfer all my music and pictures to my iPhone without the restrictions code? Also if I can't, then will I be able to download my music that I've backed up onto my computer from my iPod to my iPhone with a new apple ID?
