I JUST received a message from my reliable Roger's informant.  Here's the word:

"The 8310 is the 2nd of 7 data devices to launch for Rogers’ Q4. Corporate Reps are expected to receive early demo units in early September to use."

Every message I have received from this source to date has been correct! If you're thinking about buying a 8300 Curve from Rogers you may want to hold off for now. If the reps are set to receive them in early September it should only be a week or two later when they hit Roger's outlets across Canada. Earlier reports had the release date of the 8310 pushed back, but hopefully this news proves otherwise. I'd love to be sporting a Rogers 8310 before September is done. WooHoo!
