本文是Service Book的初探，有必要的话或需求的话，我会更深一步讲解。

首先介绍如何访问机器上的Service Book，要实现这个功能，我们可以参考一下API，API已经提供了相关的接口了。代码如下：

 ServiceBook sb = ServiceBook.getSB();
 ServiceRecord[] srs = sb.getRecords();

通过ServiceRecord，我们可以得到什么内容呢？

• CID，比如邮件的CID为CMIME，可以通过srs[i].getCid得到相关内容
• APN,既然访问网络，APN也必须得到，这对于一些网络编程非常有帮助
• 网络地址，和网络类型
• 其他

我建议看看ServiceRecord 该类的文档，说不定有意想不到的收获。

现在给出一个完整的例子：

 public void listServiceBook()
     {
         ServiceBook sb = ServiceBook.getSB();
         ServiceRecord[] srs = sb.getRecords();

         for(int index = srs.length - 1; index >= 0; --index) {
             //identify the service record associated with a mail message service via a CID of 'CMIME'
             if( srs[index].getCid().equalsIgnoreCase( "CMIME" )) {
                //add your code here
               }
         }
      }

下面讲讲应用。

已经有很多人提出如何列出Blackberry机器上绑定的邮箱.其实这个问题非常简单。可以将上面的代码改为：

 public void listBoundEmails()
     {
         ServiceBook sb = ServiceBook.getSB();
         ServiceRecord[] srs = sb.getRecords();

         for(int index = srs.length - 1; index >= 0; --index) {
             //identify the service record associated with a mail message service via a CID of 'CMIME'
             if( srs[index].getCid().equalsIgnoreCase( "CMIME" )) {
                 ServiceConfiguration sc = new ServiceConfiguration(srs[index]);
                 logger.log("The SB name configuring is:"+sc.getName()+"/"+sc.getEmailAddress());
               }
         }
      }

代码不解释了，太简单了。知道了email地址，你就可以指定一个缺省的邮件作为发送地址。这是另外一个话题，不再这里赘述。

综合上述，所以很多问题不是不懂，而是没有仔细去看文档。

还有其他应用吗？当然有，例如：

1. 如何和Blackberry邮件系统集成
2. 如何和BES关联
3. 如何让浏览器上网
4. 如何设置网络的APN
5. 如何通过WIFI访问网络
6. 如何提供LBS服务
7. 如何设置MMS服务
8. 如何设置PUSH

以上这些应用需要Service Book，但是目前RIM从来没有公开过其格式。即使有备份的ipd文件，但是ipd文件格式往往都是网友crack的，做出来的软件也不太令人满意，希望RIM能早日发布这些格式吧，这样对Blackberry的推动是非常有好处的。

以上仅仅是我任意列出的应用，如果您对以上哪个感兴趣，可以留言，如果有很多网友想知道某个具体问题，我会另写一些文章解释之。

看看最新版本有什么新特性：

1. 附件按原来格式下载
2. HTML 邮件消息的阅读

          该特性是是这个版本最大的改变。我们可以看如下类型的文件：

• 图片
• 段落格式
• 字体

   3.支持Hotmail 帐号的集成

     该功能最大的亮点是实时接收邮件，而不是原来15分钟的提交时间。同时可以集成任何格式的Hotmail邮件。

看看Blackberry官方怎么说。

Details

This article outlines the main changes to BlackBerry Internet Service 2.5.

Attachment downloading in the native file format

BlackBerry Internet Service subscribers can save, edit, upload, and transfer attachments in their native file formats. For a list of supported native file format attachments, see KB15253. BlackBerry Internet Service 2.5 subscribers can edit native file format attachments using embedded or third-party applications. This feature requires BlackBerry Device Software 4.5.

HTML email message viewing

Subscribers can view HTML email messages on their BlackBerry smartphones, including the following file types:

• Graphics and photos, including the following:
  • Embedded images and tables
  • External images
  • Active hyperlinks

  • Font type
  • Color
  • Size
  • Effects (italics, bold)

This feature requires BlackBerry Device Software 4.5. For instructions on configuring HTML email message viewing and automatic downloading of embedded images and tables, see KB15254.

Note: For security reasons, externally linked images must be manually retrieved using the menu key.

Important: HTML content cannot be created when forwarding, replying to, or composing a new email message.

Support for Windows Live™ Hotmail® integration

Integrating a Windows Live Hotmail email account results in the following:

• Real-time delivery of email messages replaces the standard 15 minute polling interval
• No restrictions; all Windows Live Hotmail accounts can be integrated

Note: Some wireless service providers do not support integration with Windows Live Hotmail. Contact your wireless service provider for information on availability.

Windows Live Hotmail email accounts integrated using BlackBerry Internet Service 2.4 or earlier must be deleted and then re-integrated to turn on the enhanced features. For instructions on removing and integrating email accounts to a BlackBerry Internet Service account, see KB04258 and KB03087, respectively

Integrated Windows Live Hotmail email accounts must be revalidated every 90 days to continue receiving email messages to the BlackBerry smartphone. Revalidation is required by Windows Live Hotmail for security purposes. Prior to the end of the 90-day window, a message is sent to the BlackBerry smartphone advising you to revalidate.
