Mark off a couple more products from that leaked T-Mobile roadmap you've obviously been using as a makeshift bingo card. This morning, T-Mobile officially announced its version of the Samsung Galaxy Tab 10.1 — with HSPA+ support and requisite apps like T-Mobile TV and the Samsung Media Hub — as well as the Huawei-manufactured T-Mobile SpringBoard (nee MediaPad). The latter device, also an Android Honeycomb tablet supporting HSPA+, feature a 7-inch screen and 1.2GHz dual-core processor. No prices or release dates are given with the announcement, but harkening back to the aforementioned roadmap, if that holds any weight, Samsung's codenamed "Arnold" will arrive October 26th for $399, whereas Huawei's codenamed "Tallsome" is due a week later on November 2nd for $199.
