Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL

I have a V5 unit and would be interested in getting a full upgrade if I sent it off to get the soldering done.
Not sure if you wanted people to respond to that question, or you were just thinking aloud...

Still waiting for an answer from OM. (I posted a question in this thread
Friday regarding Tanatalum instead of Ceramic cap - the difference being
$0.25 vs $2 each in qty 100, and my radio guy thinks Tant is a good choice
for filtering, but waiting for word from Steve or Jeorg)  Boss said he's
willing to do the jobs, but we have no caps, can't order until we know
which ones to order.  We're also hoping to find out what "help them/reward
them" involves.  (IE, OM provide parts?  OM underwrite repair?  Cover part
of repair?  Send me a Christmas card? :)  Boss ballparked the job at $25
but nothing definite yet.  (depends in part on parts)  The only concern
they had when I showed them the pdf and my FreeRunner was regarding
damaging the housing while soldering - at which point I demonstrated
removing the board from the FR with about 30 seconds effort and they said
"oooooohhhhh....  OK then.  :)"

I find myself wondering how many V5 FreeRunners are in the field and
whether the owners thereof would want the ability to 'update' to the V6
hardware fixes.  I know of the cap on the uSD pins fix for the GPS vs uSD
issue (though not the identity of that capacitor), I don't know what change
allows a V6 to run without battery or if other differences exist.  Dropping
a cap on the two pins of the uSD socket is pretty trivial if you're already
doing SMD work, so if we're already performing the Big-C rework I'd guess
(pure personal speculation) that we could add the cap to the SD lines for
little more expense and time.
