Normally, a wireless company advertising a BlackBerry that they are going to carry isn’t a big deal. Rogers, on the other hand, advertising the BlackBerry Pearl 8220, formerly known as the BlackBerry KickStart, isn’t exactly par for course as I can’t recall a time when a wireless carrier started to advertise a BlackBerry before RIM officially announces it.
Rumor has it that even though you are seeing Rogers BlackBerry Pearl 8220 advertising now, the device won’t be available until October 4th. I think it is probably safe to assume that RIM will announce it between now and then.
