According to the::unwired, the Samsung SGH-i620 looks to be the successor to the SGH-i607 (sold as the BlackJack in the US) or SGH-i600 (from Asia). It seems to sport a front and rear-facing camera and similar specs to the i600 and i607. The i620 doesn’t appear to be quadband, meaning that it won’t be slated for the US, though there could be variants of the device produced to US spec.
