If a slide posted to the PPCGeeks forum is both legitimate and accurate, then T-Mobile customers have two pretty nifty smartphones headed their way next month in the HTC HD2 and Motorola CLIQ XT. The HD2, a device we’re positive that anyone who at least occasionally frequents this site is well-versed on, is said to drop on March 10th with the CLIQ XT two weeks later on March 24th. What on earth is the CLIQ XT? Apparently it’s the Zeppelin, the physical-keypad shunning, pure touchscreen alternative to the somewhat maligned CLIQ. Still not getting it? Well, we did see it in the silicon the other day. The question is: Will we actually see it and the HD2 with T-Mobile branding next month?
