Re: With its first in-house design. Bet it isn't.
Maybe they sketched out the case and logo.
Depends what they mean by design. I did a 4G (not Wimax or LTE) VOIP only "handset" using a PCMCIA modem using a handmade case and catalogue industrial PCBs in 2007. In a sense I designed it.
Did they really pick the chips, layout a PCB etc, assemble it, debug, do the approvals etc?
