Pardon my french. But bullshit.
You spoke to a complete and total moron of a rep.
Hell, my local reps didn't know anything about the Incredible until I walked in with the leaked equipment guide and user guide printed out about 2 weeks before launch.
You're dead right, none of the things he said is possible.
Qualcom doesn't yet have a SOC Snapdragon with LTE support, so that knocks 4g out. Not to mention that even if LTE wasn't being used, they'd still have to have an FCC filing for it if they planned to turn it on in the future.
Hidden front facing camera? Really? where? In the Optical pad?
Because the other 3 holes on the front have been accounted for. Proximity sensor, light sensor and the notification LED.
