Could the Samsung Propel Pro debut on AT&T this week?  That’s the rumor. Though we have no independent confirmation, Phone Arena is reporting that the Propel Pro is headed to AT&T on Thursday. 

The Samsung Propel Pro SGH-i627 is a Windows Mobile 6.1 Standard (non-touchscreen) slider smartphone.  As seen in this photo obtained from BGR, the screen slides up to expose a QWERTY keyboard beneath. 

Unlike other current Samsung Windows Mobile offerings, the Propel Pro is a relatively low-end device, with a price (hopefully) to match.  There’s no onboard Wi-Fi and the camera is <1MP.  It does have UMTS/HSDPA 3G, aGPS and Bluetooth 2.0 + EDR, however, and a 2.2-inch 320×320 display.  There’s also a microSD memory card slot with SDHC compatibility for cards up to 32GB (although 16GB is the largest microSDHC capacity available now).
