that's not the use case for which we tested the code

from my experience that's the cause
with 1000 message my Nokia 5300 is slow on startup, but still faster
than libgnokii which takes about 300ms to list each message (so that
it takes about 5 minutes to list 1000 messages and that's why we put
an arbitrary limit of 1024, and without user feedback waiting 5
minutes is way too long to wait)

that's right

keep NK6510_GETFILELIST_TIMEOUT at 500 and increase
NK6510_FILE_CACHE_TIMEOUT from 10 seconds to how long it takes to list
them (for OU it's at least 300 / 1000  * 2528 ~= 759, so maybe 15
minutes * 60 = 900 could work)

include/phones/nk6510.h:208:#define NK6510_FILE_CACHE_TIMEOUT	10	/* seconds */
include/phones/nk6510.h:209:#define NK6510_GETFILELIST_TIMEOUT	500	/*
miliseconds */

because in IN and in OU you have more messages than what the static
array allows, if you save a message in drafts you should be able to
read it from DR memory without changing libgnokii

for more messages change
include/gnokii/sms.h:42:#define GN_SMS_MESSAGE_MAX_NUMBER    1024

if they were caused by unhandled frames you should find them in
~/.cache/gnokii/gnokii-errors
