Windows Phone 7.8，图片来自 Windows Central最坑的一次是在所有 Windows Phone 7 手机都无法升级到 Windows Phone 8，包括刚刚推出不久的旗舰机型 Lumia 900。微软为这些用户提供一个折中方案：把 Windows Phone 7 升级到 Windows Phone 7.8。Windows Phone 7.8 仅会带来部分 Windows Phone 8 的新特性，比如可调整大小的磁贴和更新后的开始界面，并且 Windows Phone 8 的应用不能向下兼容到 Windows Phone 7，不过开发者只能选择分别为 Windows Phone 8 和旧系统（包括Windows Phone 7.8）开发对应版本。

Storing Data: To write data, a high voltage (around 15-20V) is applied to the control gate above the floating gate. This causes electrons from the transistor’s channel (the substrate) to “tunnel” through the thin oxide barrier via a quantum mechanical process called Fowler-Nordheim tunneling. The electrons get trapped in the floating gate, creating a negative charge. The presence and amount of this charge shift the cell’s threshold voltage—the voltage needed to turn the transistor on during a read operation.，更多细节参见搜狗输入法下载
