Seeing how MiFis and other mobile hotspot devices have quickly become a staple of doing business for us, we had a few lying around and figured we'd give it a shot: connect the phone to the MiFi, connect the MiFi to the 3G network, and give FaceTime a whirl. Our first attempt -- a call between Chris in the US with a Verizon MiFi and Richard in the UK -- failed pretty miserably (unlike our transatlantic Fring call), but a second call entirely within the UK using a 3-branded MiFi from Huawei worked quite well, as did a US-to-US Verizon call between Chris and Ross. In other words, it's definitely possible, but you might not get as flawless of an experience as you'll get with a nice, fat landline data connection backing you up. Follow the break for all three videos.
