Motorola DVX passes through FCC, could cost $200 off-contract
There are a few UK retailers that already have pages reserved for these devices, and label the listings as the Motorola DVX. One listing says that the 8GB model will cost £155.98 including VAT (~$243), though one has it even cheaper at £137.29 including VAT (~$214). The 16GB model is listed for £150.74 including VAT (~$234). These are unlocked prices, and would definitely hit that low-cost market. And, given that U.S. prices are often less, $200 less isn't out of the question for off-contract.
Additionally, a couple of the listings say that the devices will be restocked on September 11th. That seems a bit far fetched, considering we haven't had an announcement or any official info on the device. All we do know so far is that the DVX could have swappable backplates.
