One of our solid connects told us some pretty interesting information regarding the BlackBerry slider device.

According to them, the device actually failed in early diagnostic testing a whopping 4 out of 5 times (which is supposed to be extremely rare for RIM devices). The only other handset that failed, we’re told, is the BlackBerry Pearl Flip. What’s even more interesting, is that the BlackBerry slider our guy saw was Sprint branded. Want to go one step further? We’ve been told there is also a GSM/HSPA version and that the model numbers are BlackBerry 9900 and BlackBerry 9930. Lastly, it looks like the HSPA version of the device will support 850/1900MHz UMTS bands which would make it compatible with both AT&T and Rogers’ 3G networks.

Could Sprint be gunning for an exclusive on the brand new BlackBerry form factor? Our bets would be yes.

P.S. Our guy didn’t see the word “Bold” anywhere in relation to the sliding BlackBerry device.
