305 can only be dumped - it cannot be freely edited. (The only update operation 305 does not allow random access writes: it allows random access reads like all

311 The command to dump the LND cyclic store is 'lnd-dump'. If you have had your 311 tinkering ability. The following commands are available:
312 SIM for a very long time, having used it in different phones with different 312
313 firmwares, it may be interesting to look at the output of lnd-dump - you may 313 lnd-dump
314 have LND records that were generated ages ago by other phones if your current 314
315 one does not write into SIM LND. 315 This command dumps the content of the LND store on the terminal, in the same
316 format as pb-dump for regular phonebooks.

318 If you have had your SIM for a very long time, having used it in different
319 phones with different firmwares, it may be interesting to look at the output of
320 lnd-dump - you may have LND records that were generated ages ago by other
321 phones if your current one does not write into SIM LND.

323 lnd-dump outfile
324
325 This form of the lnd-dump command produces the same dump format, but saves it
326 in the named file instead of sending it to the terminal.
327
328 lnd-restore filename
329
330 This command reads the named phonebook data file (presumably written previously
331 with lnd-dump) and writes it into EF_LND on the SIM. This command works by
332 first constructing a full binary image of the desired EF_LND content, then
333 writing every record in the reverse order from the last index to the first.
334
335 lnd-write phone-number [alpha-tag]
336
337 This command writes a new record into the LND cyclic store just like a standard
338 phone would do when making a record of a new outgoing call. The two arguments
339 (one required and one optional) are the same as for pb-update-imm.
340
341 lnd-erase
342
343 This command erases the EF_LND cyclic store, making it appear as if no outgoing
344 calls have ever been recorded. It works by writing a blank record (0xFF in
345 every byte) N times, where N is the size of the cyclic store in records.
