Samsung already made it clear that the Galaxy S5 would reach AT&T when it launched globally in April. Still, it's nice to know the flagship is on track for an on-time arrival, right? The 5.1-inch phone just surfaced in a fresh set of FCC documents, which show a GS5 variant with AT&T-friendly LTE bands (2, 4, 5 and 17) and support for ANT+ sensors (handy for wireless heart-rate monitors and the like). Predictably, the phone also includes GSM, GPRS, EDGE and UMTS, for when you can't manage a 4G signal. That still leaves lots of questions -- how much will it cost? How good is this thing? -- but we suppose we'll just have to wait until April 11th to find out.
