We're not sure exactly what the deal is with this rather plain-looking candybar, but as far as we can tell, it's not something Sony Ericsson has announced -- and that makes it interesting, even if its appearance leaves something to be desired. Our best guess is that it's a follow-on to either the V630i or the K610i, due both to the similarity in model numbers and in handset design. That doesn't totally jibe, though, because the V640i is coming in as part of Voda's holiday lineup -- and it looks decidedly lower-end than the K610i -- so your guess is as good as ours. We think we can make out a "3.0 Megapixel" badge adorning the lens on the rear next to a positively gargantuan speaker (no complaints here!). Up front, the secondary cam suggests 3G, a hunch confirmed by the test report's listing of UMTS 2100 alongside GSM 900 / 1800 / 1900 and Bluetooth 2.0+EDR. We're guessing we won't see an Americanized version of this one down the pike, and frankly, that's just fine by us.
