T-Mobile has released details about the Samsung Galaxy S 4G and G-Slate tablet. The Samsung Galaxy S 4G works on the T-Mobile HSPA+ network and will launch later this month. It has a front-facing camera for video chat and support for mobile HD TV content. T-Mobile did not say how much it will cost. T-Mobile SVP Andrew Sherrard said that there is no point of having an iPhone when the network is inferior. ?Why would you upgrade your phone and downgrade your network?? said Sherrard. T-Mobile released some details about the G-Slate tablet too. The G-Slate has the ability to display 3-D content (glasses required) and can record 3-D movies using built-in stereoscopic cameras on the back of the tablet. The tablet has a dual-core 1GHz NVIDIA Tegra 2 chip, 32GB of memory, and Adobe Flash support.
