[GreenKeys] BSP vs TC - not the same??

[w9ddd at tapr.org]

Heck I just recently noticed there were different versions.  Now I got to pay attention to issues numbers?  

The only reason I figured it out was I was puzzled by the iPad trying to make phone numbers out of 573-000-001 and not 573-000-002TC.  (Not necessarily valid numbers, examples only).   I kept getting asked if I wanted to call that number.  The TC at the end tells iPhone it's not a phone number.

 I guess no one at Apple remembers numbers like Alpine 5-3289.  (AL5-3289 would blow up your iPhone?)
