My iPhone 4 screen cracked from me stepping it by complete accident. It's the first phone I've broken, would it be a wise decision to switch to a Windows Phone?
Also, I feel like Windows Phones could really do well if they did a Pay As You Go thing that still allows unlimited internet usage. I'd buy the crap out of that deal.
You can switch to windows phone but i will still recommend you to not leave iphone, i mean iphone is the most exclusive thing people ever encountered. Windows is quite smart option but iphone is brilliant option, and if you want to switch to windows from iphone for unlimited internet usage then you should not go with iphone or windows phones you should move to android phones. They are pretty simple, easy, fast to operate and using Internet in android would be your religious experience.
