Samsung has sprung an early surprise in advance of the Mobile World Congress show later this month, unveiling a new model in its Galaxy Tab range of Android tablets. The Galaxy Tab 2 (7.0) has a seven-inch screen, and runs the latest version of Google’s Android software: 4.0 Ice Cream Sandwich. The tab has a 1GHz dual-core processor, and will come in a choice of Wi-Fi-only or Wi-Fi plus 3G versions. Content-wise, the Galaxy Tab 2 will include Samsung’s Music, Reader and Games hubs for downloading music, e-books and games. There’s also a new Video Hub, which will have more than 1,000 films available to rent or buy. There’s also a new service called AllShare Play, which will let Galaxy Tab 2 owners stream multimedia content from PCs, other `smart’ Samsung devices (e.g. smartphones and TVs) or cloud storage services.
