Somehow, Engadget has got its hands on the launch schedule for the Three network for the summer months and while much of it is confirmation for devices we've already seen, one device is all-new - the Samsung Galaxy S II Mini.Not to be confused with the Galaxy Mini or the Samsung Galaxy S II, this looks to be a smaller version of the latter, but not as 'mini' as you might be expecting. According to the details given, it's got a 3.7-inch capacitive touchscreen, a 1.4GHz processor and 21Mbps HSPA+ connectivity, along with a 5-megapixel camera with LED flash, a front-facing camera plus Android 2.3 (Gingerbread) for the operating system.It is described as a 'high end' phone and is down for a shelf date of April. With no official launch for the handset as yet, that's going to be some turnaround.Other snippets of note show the Nokia X7 set for a June release, alongside the LG Optimus 3D. Tablets confirmed too, including the HTC Flyer in May and the WiFi-only BlackBerry PlayBook in June. A busy few months for Three then. More on all of this when we hear the official word.
