We’ve heard that AT&T’s GPS-ified BlackBerry 8310 is set for launch on September 24th, which would line up well with a their Pearl 2 debut mid-September. The talk about BlackBerry 8800s getting phased out to make room for the 8820 gets you wondering about how long it will be before the BlackBerry 8300 gets the same treatment. If there’s no significant price difference, is there a reason someone wouldn’t go for the 8310 over the 8300? Hell, if the BlackBerry 8310 is going to be in black, it’s a done deal – anyone who hadn’t gotten around to picking up a Curve will just grab the newer model. All these new devices are fun and all, but should RIM be spacing out their product releases a bit more to give them time to sell?
