Where to learn to hack and crack?

I have always had a passion of wanting to hack or crack into things like iPhones or making programs that hack into websites. But I ran into one problem. I'm only 13, can't go to college to learn to hack, only hack 226 dollars of money able to spend, and I don't know how to do it or where to learn. I'm learning how to use html on code academy because one site said it's a helper to know html when hacking. I'd read the hacking for dummy's but I don't like to read. I have a really high reading level but I read very slow. Is there like a website or a place where people are willing to teach. I live in California I don't know if that would help.

Is something wrong with iPhone?

I own an iPhone 4s locked to Verizon. I've been trying to unlock it using a GPP and have been taking my sim tray out a lot. Now when i take it out, it doesn't say "sim not inserted" anymore. The message doesn't pop up anymore, did i break something? It still reads my sim card and all but the message just doesn't show.
