What does each cellular connectivity indicator mean? I'm used to &quot;3G&quot; and &quot;E&quot; on my AT&amp;T iPhone 3GS, and I understand I may see &quot;4G&quot; on my new iPad when I enter a 4G area.
However, I recently saw &quot;o&quot; on the new Verizon iPad, and had no idea what it meant.
What network connectivity indicators can I expect to see on my iOS devices, and what do they generally mean?
Are the connectivity indicators the same for all iOS devices (with expected carrier differences) or should I assume &quot;3G&quot; on the 1st gen iPad means something different than &quot;3G&quot; on the new iPad?
The "o" means that you're on a 2G network. In Verizon's case, that would be 1xRTT. If you see it on an AT&amp;T device, that means you're on GPRS.

Here's a screenshot from the iPad User Guide detailing what the various signal indicators mean:



"3G" means exactly the same thing on the 1st generation iPad as it does on the 3rd generation iPad. However, if you have AT&amp;T, the 3rd generation iPad reports HSDPA+ as "4G". Since the 1st generation iPad is incapable of using HSDPA+, you will only ever see 3G or below on that device.
