我怎么知道我的iPhone / iPad是连接到2G还是3G？ [英] How do I know whether my iPhone/iPad is connected to 2G or 3G?

问题描述

我试图检查设备是通过2G（GPRS，EDGE）还是3G（UMTS，HSDPA）连接的。

I was trying to check wether the device is connected via 2G (GPRS, EDGE) or 3G (UMTS, HSDPA).

我只找到了Reachability示例类来自此处（Apple Dev示例）

I only found the Reachability example class from here (Apple Dev Example)

此示例仅检查其Wifi或WWAN。我想用它来决定下载小数据还是大文件。由于GRPS和UMTS之间存在很大差异。

This example only check wether its Wifi or WWAN. I wanna use it to decide wether I download the small data or the huge files. As it is big different between GRPS and UMTS.
