Your just being ignorant, if you do look up for reviews then you would know. iPhone 5 is a good phone, it's simple and fast, guess what some people just don't care about customization. Lumia is also a great phone, phone itself is like a rock. Nokia really proved them self with Lumia 920
On topic: Both are great phones but I like Lumia 920 better.
Both are still shit.
You don't have to base your view by checking reviews. Especially phones, it's very personal. Just try the phone, and buy it. Don't look at reviews.
I'm a happy BlackBerry user. I also have the Galaxy S3.
