Tonē Hufford's dashboard

While in the settings menu, I noticed that the tab for "Devices" is pleural. I this in the FAQ:

"Can I use the same phone number on multiple accounts, or have multiple phone numbers for the same account?

No. You can only use one phone number for one account."

So does this mean you can only use one device to send updates? But then again, I guess it would be using another number if you wanted to use Google Voice SMS for Twitter, right?
