Note 0: SMSC : SMS Center!
Note 1: It may be necessary to change the prefix from the set of (*#, **, ##) to
initiate a new log dump. The logs are not “tail” able, since this is a single
dump, with no additional data written. So far, these logs appear to always
remain the same size. Logfiles are stamped with the current date.
Note 2: These tests were performed with a stock phone on the AT&T network. It is
possible that these errors represent debugging features that are only
available on a special debug cellular base-station (CONJECTURE only!)’
