为什么移动操作系统仍然与供应商挂钩？
现代移动电话自 30 多年前诞生以来已经取得了长足的进步。尤其是智能手机，它本质上是微型个人电脑，能够完成所有相同的事情，只是速度慢一点。那么，如果手机已经追随个人电脑的脚步，为什么他们的软件却没有呢？为什么我不能拿起我的手机并在其上安装最新版本的 Android，就像我在 PC 上安装最新版本的 Windows 或 Ubuntu 一样？这仅仅是一个营销决策（市场隔离，如果您想要不同的操作系统则强制购买新手机等），还是存在一些根本问题阻止了良好的旧操作系统+驱动程序模型？
Modern mobile phones have come far since their beginnings over 30 years ago. Especially smartphones, which are essentially miniature PC's, capable of all the same things, if at a bit slower pace. So if cellphones have followed in the footsteps of PCs, why hasn't their software? Why can't I take my mobile phone and install the latest edition of Android on it, like I install the latest edition of Windows or Ubuntu on my PC? Is this solely a marketing decision (market segregation, forcing to buy a new phone if you want a different OS, etc.), or is there some fundamental problem preventing the good old OS+driver model?

可能是因为没有必要。手机就像烤面包机。几乎没有人愿意更改烤面包机的固件（Cylons 除外）。大多数人只是想使用它。
可互换的固件意味着供应商需要做额外的工作，如果没有人会使用此功能，那么这是不合理的。
Probably because there was no need for it. A cellphone is like a toaster. Nearly nobody want’s to change the firmware of a toaster (except for Cylons). Most people simply want to use it.
Interchangeable firmwares mean additional work for the vendor which can’t be justified if nobody will use this feature.
您可以通过 root您的手机。事实上，将 Android 移植到 iPhone 上是可能的（理论上也可以做相反的事情）。它并没有更广泛，因为手机和软件紧密地联系在一起，这就是为什么你永远不必担心驱动程序。如果您要更改操作系统并执行其他需要类似级别的访问和修改的任务，则需要制造商更新所有这些具体细节，因此这种情况很少见。过去，有些手机（例如 Omnia）制造商会为用户提供这些更新。
You can do that, by rooting your phone. In fact, it is possible to put Android onto iPhone (and theoretically possible to do the opposite). It's not more widespread because the phone and software are tied together very tightly, that's why you never have to worry about drivers. For you to change the operating system and perform other tasks that require similar levels of access and modification, it requires manufacturers to update all those specific details, hence it is rare. In the past there have been phones (such as the Omnia) where the manufacturer provides these updates for owners.
