I also called my local T-Mobile stores and they have not yet received their allotment of 8320's. Other members have stated that stores will be receiving or have received 5 golds and 5 titaniums. I'm pretty sure this will be the scenario come Monday:
9am Monday @ your local T-Mob store
<Joe user off the street> Hi, I'd like to purchase a Blackberry Curve 8320 please
<T-Mob counter dude/dudette> I'm sorry, we don't have those models yet.
or
<T-Mob counter dude/dudette> I'm sorry, we are sold out already.
1:34pm Monday @ your local T-Mob store
<friend of T-Mob counter dude/dudette> Hey, thanks for holding one for me! Man this thing is SWEET!
<T-Mob counter dude/dudette>No problem. Hey, when you see Doug, let him know his is back here too!
