The HTC Evo 4G isn't a QWERTY phone though? https://www.gsmarena.com/htc_evo_4g-3427.php

Even doing a Google search for "Sprint EVO 4G" doesn't reveal a keyboard.

Do you have the gsmarena link to the exact model?

Edit: Did further digging, seems like you're talking about the HTC EVO Shift 4G. If so, you should update your blog with the correct model name.
