Greg:

My QST article says this:

Greg, NV6G, has announced a beta-application for the iPhone that
has implemented APRS messaging support through OpenAPRS's DCC
interface.11 It also enables a ham's iPhone to be tracked using
its GPS through the Internet network to OpenAPRS's servers and
out to the APRS-IS. Both systems follow OpenAPRS's license
verification system. Look for the software sometime in late
November 2009. 

Is there a reference web page?
Need this by tomorrow?

Bob, WB4aPR
