symbian s60 第 3 版 FP2 版本是否向后兼容 s30 第 2 版 FP3？
我已经在 symbian s60 3rd fp2 中开发了应用程序，我想在需要 symbian s60 2nd Edition fp3 的诺基亚 N72 中对其进行调整，我也是如此需要进行不同的构建或其向后兼容第二版 fp3？
谢谢。

它不向后兼容。 S60 第 3 版基于 Symbian 9，S60 第 2 版 fp3 基于 Symbian 8。Symbian 8 和 9 二进制不兼容。好消息是，S60 第二版尚未引入平台安全概念，因此移植工作应该相当容易。
It is not backwards compatible. S60 3rd edition is based on Symbian 9, and S60 2nd edition fp3 is based on Symbian 8. Symbian 8 and 9 are binary incompatible. The good news is that the platform security concept was not yet introduced on S60 2nd edition so the porting work should be fairly easy.
S60 3rd FP2基于Symbian OS v9.3，而S60 2nd FP3基于Symbian OS 8.0 a或8.1如果我记得的话，它是非常非常旧的版本。源代码或多或少会兼容，但是您需要进行某些更改，特别是准备 sis 文件，因为例如应用程序资源、图标格式和应用程序二进制格式（exe 与 app）发生了变化......我建议您不要尝试支持那些旧手机...我什至不确定 SDK 是否仍然可供下载，并且您可能不被允许使用它去 Ovi 商店。但我在这里不确定 - 请自行检查。

the
S60 3rd FP2is based on theSymbian OS v9.3, while theS60 2nd FP3is based on theSymbian OS 8.0aor8.1if I remember and it is really, really old version. The source code will be more or less compatible, but you will need to make certain changes especially to prepare the sis file, since e.g. application resource, icon format and the application binary format (exe vs. app) changed...I suggest you to not try to support those old phones... I am not even sure if the SDK is still available for the download and you might not be allowed to go to the Ovi store with that. but I am not sure here - check it on your own.
