None of the LG phones use the retry code.  I initially added it to try
and work around the VX4400 USB issues, then removed it, and then it
got re-added.  I think Stephen uses it for some of the Sanyo phones.
The big problem is that retries are only useful for stateless stuff.
If for example you send a command like 'advance to next entry' and
get a timeout reading the response, how do you know if the action
happened or not?  The sensible precaution is to start over again,
but usually you would hit the same issue in the same place or
earlier.

There is a 0.3 second delay after getting each file when making a zip
backup.  I found some phones (cough LG cough) would eventually crap out.
I think their other tasks running on the phone getting starved for CPU
or something similar.

Wherever possible it is preferable to use the sync protocols rather
than modify the filesystem directly.
