According to blog TmoNews, T-Mobile will release the G-Slate tablet and G2X smartphone next month on April 20th. The blog notes that the two LG devices should be given firm release date on the nation’s fourth largest provider next week at the CTIA Wireless conference in Orlando, FL. The LG G2X will be a T-Mobile branded Optimus 2X and the G-Slate is the Honeycomb device we saw announced at CES back in January. We know the G-Slate will be sporting an HSPA+, 4G radio, but details on the G2X are still unknown.
