T-Mobile on Tuesday made a late commitment to full launch details for the LG G-Slate. Its adaptation ships tomorrow, April 20, for the promised $530 on a two-year contract, though only for existing T-Mobile phone subscribers; the price rises to $630 for others. The Android 3.0 device now has a contract-free price but will set users back $750 in its lone 32GB edition, or $20 more than an equivalent iPad 2.
