I can tell you why. Cause there are a lot of people who are just talking BS to harm the other "group". I will repeat it till my dead I never had any issues with Macs, iPhones, iPads and iPods. I can't reconstruct issues people have and until I see a iPhone which crashes 5 times a day I won't believe it.
Plus if you have so much trouble with you phone, what about calling Apple and telling them your issue. When I called last time because a failure they send me immediately a brand new device. Sorry mate but something seems odd.
I don't want to attack you personal, it just seems that a lot of people are trying to talk BS about Apple products.
