1. 安全性 黑莓的安全性没的说的：重启自检，虽然重启慢的一塌糊涂。没有病毒，且没有杀毒软件表示要做黑莓版杀毒软件。不然奥巴马怎么敢用黑莓呢？此外，黑莓对 API 的调用只能通过一个软件：如邮件弹出，不能装两个类似的软件。另外，黑莓不能随意篡改系统文件。 iPhone 和 Android的安全性一般，系统文件可以随意篡改。很多底层的软件包括内置软件都会出现不稳定的情况，第三方应用更是容易崩溃。 Continue reading »

Research In Motion executives are fond of saying that their platform is more secure than other mobile providers. For example, Scott Tzoke, RIM's VP of Security was recently quoted as saying that BlackBerrys are “secure right out of the box” (meaning that no additional mobile security protection is needed) and that RIM offers enterprises with the most secure mobile computing option thanks to the ability to create security settings for all enterprise users via its BlackBerry Enterprise Server (BES).
This official position is not without its critics, particularly among some mobile security researchers such as Tyler Shields whose presentation at ShmooCon 2010 showed how standard BlackBerry settings could “access and leak sensitive information using only RIM-provided APIs and no trickery or exploits at all.”
All of these security questions are moot, however, if you're using your BlackBerry to send its highly touted encrypted emails to or from the Russian Federation, the Peoples Republic of China; or, shortly, India, Saudi Arabia and the UAE. Continue reading »

问题描述:
1. 在启用firewall的情况下, 程序第一次使用cmnet上网后,不能使用wifi来上网; 程序第一次使用wifi上网后,不能使用cmnet来上网.
2. 关闭firewall后才可以上. 黑莓自带浏览器不受影响.Goonuu不受影响.
3. 现象,不能连接时提示: The application has attempted to open a connection to a location inside the firewall and outside the firewall.
原因剖析:
1. 在黑莓出厂的默认设置中, 为保持手持设备的网络安全,禁止了第三方程序的private和public两种类型连接方式的共存,以保护内部网络数据不被第三方程序传送到public网络. 例如黑莓企业服务器的MDS输入private类型,而wap和cmnet属于public类型.
2. 此项控制是通过手机IT Policy中 “ALLOW_SPLIT_PIPE_CONNECTIONS” 这一条策略来调整,出厂默认为False.需将其设置为True才可以使用多种类型上网方式.
解决方法:… Continue reading »

Some key features:
