Diego Magnani over at WindowsMobileItaly.com has posted a review of Samsung’s C6620 smartphone. This is one of the devices that Samsung showed off at Mobile World Congress earlier this year. The device is running on Italy’s TIM network and sold under the MVNO (Mobile Virtual Network Operator) MTV. Samsung has produced a number of devices based on that BlackJack footprint and it looks like this approach is working very well for them. Each version has some slight modifications. With this version, they have increased the screen size from 2.4 to 2.6” and removed some of the network radio’s. This phone is great for use in Europe, but doesn’t fair well when it’s brought to North America.
