The first hint of the arrival of HTC’s new One series of smartphones in the US has emerged, with leaked screenshots from T-Mobile suggesting that the operator will launch the HTC One S as early as April 25, according to Tmonews.

Unfortunately there’s no mention of dates for the One X and the One V, the other devices in the series, at the stage, according to the screenshots that are said to come from the operator’s employee training program. However, HTC is widely expected to bring the three devices to market at some point this month.

The imminent launch of the range, which was unveiled in February at the Mobile World Congress event in Barcelona, comes at a time when HTC has reported a troubling set of weak earnings for the first quarter of 2012.

Amongst the figures, the Taiwanese firm saw net revenue for the three month period decrease 35 percent year-on-year, while net profit plunged by 70 percent.

HTC believes that by concentrating on ‘hero’ phones, it can reverse its decline and intensify competition in the smartphone market again. The One S is very much a key to that and it will be interesting to observe the reaction that its launch receives in the US.

The One range gained glowing praise from The Next Web’s news and mobile editor Matt Brian, who gave them a spin in Barcelona and can’t wait for the full release:

Playing with the devices, it is clear to see that HTC is back to its best, offering sleek, sexy devices that have the necessary power and features to make consumers consider them from their competition.

We’ll keep you posted with more details as we find them.
