We just found out the Android-tastic Sidekick 4G would be launching on April 20th, and it looks like he’s bringing friends: also launching on the 20th will be the T-Mobile-branded version of LG’s Optimus 2X, dubbed the “G2X” here.
While this won’t be the first dual-core Android phone in the US (that title went to the Atrix), it’s the first one to hit T-Mobile — and power comes with a bit of a price tag. Expect the G2X to cost you $250 out the door on a 2-year contract, though a $50 mail-in rebate will take some of that sting off.
