BlackBerry手机上Java程序如何判断当前手机使用的运营商网络名称？网路制式？

你可以使用RadioInfo API了解相关信息，拿到的信息如下：

	Network Name	Network
9650 + China Telecom	乱码（(手机中文或者英文界面都是乱码， 电信工作不给力啊）	CDMA, 3GPP  GPRS  WiFi
9900 + China Unicom	China Unicom(手机英文界面)  中国联通	3GPP  GPRS  WiFi
9788 + China Mobile	CHINA MOBILE(手机英文界面)  中国移动	3GPP  GPRS WiFi
