LG's U.S. launch plans for the G4 are all coming together, as another major U.S. carrier has announced its launch plans for the company's latest and greatest flagship smartphone. Sprint recently announced that it will begin selling the LG G4 online and in retail stores beginning on June 5. Best Buy just announced that it has opened preorders for the LG G4 on Verizon, Sprint and AT&T and is including a free $100 gift card for customers who preorder the handset through it.

T-Mobile fans waiting for official LG G4 launch news now have a solid release date, pricing and free 128 GB microSD card offer from the carrier. T-Mobile will open up online sales for the LG G4 on Wednesday, May 27 at 6 a.m. PDT for $0 down and $24.99 per month for 24 months, which comes out to $599.76 full price.

T-Mobile is also including a free 128 GB microSD card with the order, which it notes is actually five times more memory than the 32 GB of internal storage the smartphone ships with. The carrier will begin shipping the G4 to online customers ahead of its scheduled in-store release of June 3.
