Some new evidence has surfaced saying that the T-Mobile G2x – their version of the Tegra 2-enabled Optimus 2X – will be launched April 15th. Earlier rumors pegged it for an April 20th launch date, but the only T-Mobile device confirmed to be launching that day is the T-Mobile Sidekick 4G. We also heard murmurs of LG’s tablet – the T-Mobile G-Slate – being released that very same date, but that is still very much up in the air. The 15th is just over a week away so we’ll see soon enough if this document isn’t telling any fibs. [via Android Central]
