Is Windows Phone 8 a new threat to the iPhone?

Is Windows Phone 8 a new threat to the iPhone?

I don't think so. The biggest competitor is Android.

I have not tried Windows phone but if it is anything like Windows 8 on laptops, I doubt it.
I think IOS 8 and bend and break iphones are the biggest threat to iphone but I'm an Android user

Not really. Been out for several years now, no threat.
