Correct.

No.  Look at the savephonebook code.  That code re-reads the phonebook,
and matches up the serials of the data about to be written with what is
already on the phone.

The VX4400/4500/6000 require that you write out stuff in entry order,
but there can be holes due to entries being deleted, and then new entries
are appended.

It would be pointless storing the entry number in BitPim since the 
phonebook on the phone could change between BitPim reading it and
BitPim writing to it.

This has nothing to do with Brew.  The LG phones store their phonebook in
files particular to them and have their own sync protocol.

The phone has a file containing the next counter number.  When you add an
entry, that number gets allocated.

Just make sure you do a complete filesystem backup first and you should be
ok.  About the worst damage is if the phone gets into an infinite reboot
loop, in which case Verizon will replace the phone.

The speeddial is not read as it isn't included in the phonebook sync protocol
as far as I can tell.  It is on a file in the phone, but I haven't quite
figured out how it is stored.  The speed dials (and voice dials) are tied to 
particular serials, so providing the serials of entries are preserved the
speed/voice dials are preserved.

What a few weeks till bitfling is ready (I'll give more details when it is
closer to completion).  It will make development considerably quicker and
easier for phones not in front of you.
