Can I use an inactive IPhone 3 to use as a second device with a second reader I have?

yes, you can use old iPhones as alternate payment devices, but an iPhone 3g or 3GS are too old to be used with Square.  the oldest that is compatible I believe is the 4s.

Just remember you'll need to connect to wifi to process payments @dave47859! 🙂
