刚才用UCWEB，发现有最新版本，用UCWEB本身升级，提示无法下载Jar文件，于是在UC官网去下载。我手机是索尼爱立信M600i，找到相应版本的UCWEB，其实就是JAVA通用版本，下载了Jar文件，传到手机记忆卡，安装位置选择记忆卡，提示：授权失败。在UC论坛里找了找相关的帖子，没多大用处，都说是记忆卡的问题。突然想起是不是Jad没一起拷贝到手机的原因，于是拷贝Jad和Jar放在同一目录下，同名，点击Jad文件，提示无法下载Jar文件，在电脑上用UltraEdit打开Jad，内容如下：

把MIDlet-Jar-URL段改成："MIDlet-Jar-URL: UCWEB-7.2.2.51-999-70-10051816.jar"。拷贝进手机，用Jad安装，OK，可以安装了。看来UCWEB在安装的时候得确认MIDlet相关内容。
