Far from being the first dual-mode
handset we've seen
(heck, it's not even the first WiMAX-friendly dualie
), Qsida's recently showcased slider is still quite intriguing. The currently unnamed cellphone supports both 802.16e WiMAX as well as GSM / GPRS / EDGE networks, and just in case you're hankering for another way to get connected, there's a built-in WiFi module too. Reportedly, the smartphone is a test device used in the M-Taiwan initiative to promote WiMAX, and aside from handling voice calls via (almost) any flavor of wireless protocol, you'll also find Windows Mobile 6.1 running the show. Granted, this particular unit wasn't down with 3G, but a spokesperson was adamant that such a handset would be added to its portfolio eventually.
