The index files look like this:
2 UINT numentries
* LIST entries:
2 UINT id
50 STRING name # different number of bytes on each model
The overal file is a fixed number of entries long (typically 20 or
30). The id is what is used in the phonebook etc to refer to that
entry. Entries with an id of -1/0xffff are unused. This does
mean that the numentries field and the number of entries with
a valid id could differ.
When you delete something on the phone, it usually just changes that
entry to have an id of -1/0xffff. Consequently you have "holes"
in the entries.
When writing a new index file out, the code always writes them
in id order. No holes are left. New entries are given the
lowest free id number.
