A more detailed Verizon roadmap has surfaced today that not only provides more color for its tablet and smartphone plans but suggests trouble for RIM. The Motorola Stingray tablet was supposedly verified as real by the Engadget source and should be a 10-inch, Android 3.0 flagship device running on a dual-core NVIDIA Tegra 2 and 16GB of storage. Unusually, it would only ship with 3G but would be "hardware upgradeable to LTE" for 4G, presumably through a card or a USB modem.
