Earlier this summer, the Samsung SGH-i620 popped-up the first time and it looks like we are close a launch. As expected, Vodafone is carrying the i620 or in this case Vodafone UK.
Feature-wise, the i620 is a kind of updated i600. It's coming with Windows Mobile 6 Standard (Smartphone) preinstalled and features an updated 2 megapixel camera. Furthermore, it supports GSM/GPRS/EDGE as well as UMTS (while HSDPA is expected also).
Like the i600, also the i620 features a QWERTY thumb-keyboard but this slides out which makes the device on one hand shorter, on the other hand a little bit thicker:

Vodafone hasn't given a launch date yet, the Samsung SGH-i620 just appeared on Vodafone's "coming soon" page. Also the retail price is unknown yet but I hope to get more information soon - stay tuned.
