Samsung 'Jack' coming to, er, staying at AT&T?

We're not quite sure what's in store here, but the Samsung "Jack" has appeared on an AT&T rebate form, courtesy of the Boy Genius Report.

We know the Jack as the Canadian version of the i617 Blackjack II. The two phones are identical, except one just goes by "Jack." The one we see listed here is the i637 "Jack." We've actually seen the i637 before at the FCC, when we thought it might be the Propel Pro. (The Propel Pro turned out to be the i627.)

So, it looks like we might have a slightly updated Blackjack II on the way. What would you guys like to see fixed in one of the more popular Windows Mobile phones out there?
