We’ve been hearing about the Pantech Duo 2 for what seems like years (it’s actually been about nine months), but now it looks like the wait will soon be over.

Contrary to our previous reporting, however, the new Windows Mobile 6.1 Standard Pantech smartphone probably won’t be called the Duo 2 when it hits store shelves, even though it’s obviously the follow-up to the current Pantech Duo. 

A newly released rebate form AT&T Wireless lists the C820 as the Matrix Pro.  This actually makes a lot of sense, being that a similar-looking device from Pantech, the Matrix, is already available from AT&T. The Matrix is a multimedia-enabled dumbfone, so it would appear the Matrix Pro will be the smarter sibling.

No word yet on a release date, but we assume based on that rebate form,  the Matrix Pro C820 is coming sooner rather than later.
