New year, more dumped phone firmwares!

Thanks to consistent lender Rare Noggin Stuff for sending these over:
#Audiovox CDM-8500 (T050BMDM02_6.189)
#LG PM325 (PM325V20)
LG VX10 (T5BVZV06)
LG VX4400 (TE4VZV10)
#Sejin NS1000
As always, what's new can be found on the Dumbphone Repo.

The Sejin NS1000 ought to get its own post some day. That simple looking phone was a bit infamous for some use cases, but the interesting part to me is how its MIDI softsynth makes heavy use of #Roland SC-55 samples!
