I think I have an exciting discovery here folks and kiddies
This is from the FCC filing of
PB31200 which is our previously unknown CDMA2000 device
Notice the model number of the batteries for the device is BTR
6300B. The BTR of course refers to "battery" but the 6300 model number matches up with what we now believe is the Incredible from the Verizon Inventory
So I think we can now say PB31200 == Verizon's Incredible. The filing cleared Feb 9 so if it keeps the same FCC->release lead time of the Eris, expect it in early April or late March.
The only other explanation is that the Incredible's battery is the same one used by another device, like the Legend, but I doubt it. The battery is 1300mAh compared to N1's 1400mAh and Eris' 1250mAh. Maybe smaller battery to make room for the bigger camera?
Updating the main
FCC thread in the Passion section too.
