黑莓应用程序可以不受限制地访问互联网吗？
我即将为黑莓开发一个应用程序，该应用程序通过本机套接字连接将一些数据传输到服务器。这可以在 Java 中轻松完成，但我被告知这种方法的问题是大多数黑莓都有某种限制的互联网访问，并且套接字连接无法工作。
这是真的吗？通常，从北美商店购买的带有数据计划的黑莓手机是否可以不受限制地访问互联网（在端口等方面）？
I'm about to develop an application for blackberry that transport some data through a native socket connection to a server. This can be done easily in Java but I was told the issue with this approach is that most blackberries have some sort of restricted internet access and that the socket connection would not work.
Is this true? Typically a blackberry bought from a store in North America with a data plan, do they have unrestricted access to the internet (in terms of ports etc)?

不幸的是，这是一个依赖于运营商的问题。例如，我知道罗杰斯黑莓拥有您正在寻找的访问权限，而我合作过的贝尔黑莓却没有。
Unfortunately that is a carrier dependent issue. I know, for example, that Rogers Blackberries have the access you are looking for, where the Bell Blackberries I've worked with don't.
