True.  Alas this is an irritating bit about the implementation of call 
waiting on the GS

I'm not sure that I would call item#2 a problem.

Not so true. On all of my GS phones (20), I now, after discovering 2 
separate problems, have call waiting working with the flash key.  It 
works on all versions of the firmware that I have tested after '3.81. 
Press once, puts 1st call on hold, answers 2nd call. Press again, puts 
second caller on hold, returns to first caller, etc. The first problem I 
had was misconfiguration of the "send flash as DTMF event" option. For 
call waiting to work, you must have this option set to false in the 
phone configuration.

(By the way, the other problem I had was a hardware problem on one 
phone: hot melt glue all over the keypad contact area.)

Alas, also true.
