If there was any doubt that the BlackBerry 9800 was headed to AT&T this should quell it. We just mentioned earlier that red and white housings were found for the 9800 and now Mac over @PocketBerry noticed that TrueSupplier is selling a black 9800 housing with AT&T branding. That fits nicely with the current rumored launch date of August 15th for the BlackBerry 9800 on AT&T. I doubt AT&T will actually launch on the 15th but hopefully they will not delay the launch like they did for the 9000 and 9700.
On a side note TrueSupplier also has a black leather pouch case and a charging pod for the 9800 so expect to see those at launch.
