Can't turn on Wi-Fi on my iPhone? - 1

This morning my home Wi-Fi wasn't working and when I was trying to connect it I accidentally turned my Wi-Fi off on my phone. I turned it back on again, or at least I thought I did? Anyway, I just checked because Wi-Fi wasn't working and it's not switched on, but it's not letting me slide the option over to switch it on. Any ideas? Help!
I have restarted the phone twice and this hasn't solved the problem.

Added (1). I have also restored it and that hasn't worked either.

Can I switch to an iphone with a blackberry contract?

I've got about 6 months left on my vodafone contract and i have the blackberry bold 9900. Its a great phone but i've always had a blackberry and now it's starting to play up so its time for a change. My friends going to give me her iphone in a few weeks because she's getting an upgrade in the new year. So i was going to go into vodfone soon and talk to them about it because the sim is alot smaller for iphones and they have to be inserted etc. Would this work? Do you think they would be okay with me doing this? A girl i know has done exactly the same about a month ago (her dad gave her his upgrade and she got and iphone even though she was still on another contract) It worked for her i hope it does for me! Any help will be useful thanks guys!
