To follow up on that question, here's a summary that I *think*
is correct.

0. The real solution is to have libmtp updated by the Redhat
developer community so that MTP mode works; until then, the 
PTP mode setup is an effective workaround - if you know the 

1. You apparently need to connect the phone once in order
to even *see* the GUI for switching from MTP mode to PTP 
mode; so after you do that, make sure you reboot the 
Centos PC with the phone disconnected from it.

2. You apparently do *not* need the updated libmtp RPM to 
use PTP mode; so your rhythmbox and vlc programs should be
unaffected by this MTP->PTP workaround

3. You apparently *must* unlock your phone before connecting
it to the Centos PC; and if you connect without unlocking, you 
may have to start all over with a Centos PC reboot (why this is 
the case is beyond me but don't fight it; just reboot and 
remember to unlock the phone before connecting it to the PC).

4. Once the phone is permanently in PTP mode, and the Centos 
PC has been rebooted without the phone being connected, you 
can *unlock* the phone, and then connect it to the Centos PC;
and the result should be your file system on the phone
being accessible on the Centos PC.

In my test just now, there was no error message whatsoever!
The workaround sounds so easy, in retrospect! :)
