I'm curious about the same thing. I have the w6, but was able to pick up a 3213 at a lower price. I've heard different things such as the 3213 is the same as w6, but BB had the model number changed so people couldn't PM for BF. I've heard that its the new model to replace w6(Which I believe the least), I've heard this was only made for BF, (which I believe happened). I haven't had a chance to open the 3213, but anyone know if they're pretty much the same set?
I know stat-wise the 3213 is better, but thats all I know.
