关于单词的大小写问题

[F2Sky]

一直有一个疑惑，像 iPhone、iPad、iOS 这些单词首字母都是小写的，如果在句首出现怎样才是正确的书写方法呢？

句首小写，感觉放在句首不大放心；

句首大写，看着又觉得很别扭。

关键是句首大写、小写网上都见到过了，不知道哪种书写方式才是规范的？

正确是 iPhone 品牌名字不能改变

我的理解是，专有名词的大小写是固定的，比如姓名、国名、商标、缩写之类的。未考据

小写，直接句首肯定没问题。不放心，加个The好了。

水果网站上根本就不把这个当问题：

iPhone 6 isn’t simply bigger — it’s better in every way. Larger, yet dramatically thinner. More powerful, but remarkably power efficient. With a smooth metal surface that seamlessly meets the new Retina HD display. It’s one continuous form where hardware and software function in perfect unison, creating a new generation of iPhone that’s better by any measure.

iPhone 6 has faster LTE download speeds,* and it supports more LTE bands than any other smartphone so you can roam in more places. And when connected to Wi-Fi, you’ll get up to 3x faster speeds.
