HTC and Huawei are both expected to bring their A-game to MWC. What exactly that entails remains a mystery, thanks to both companies keeping their lips sealed. And while we’re still not completely sure as to what secrets these devices still hold — or even their official names, for that matter — TmoNews picked up a leaked screenshot that shows off a list of upcoming accessories on T-Mobile, some of which are for the HTC Ville and Huawei Prism in April. Does this guarantee that we’ll see both devices featured on the GSM carrier? Not at all, but stay tuned over the next few days because we have a feeling more answers will come pouring in soon.
