originally din wanna consider mifi... but looks like it might be the easier option for me. so need to ask sifu here (coz i dun have any mifi experience):
* can i set the dns settings on the mifi -- i prefer to use openDNS & googleDNS. i know for PC can set this on the PC, but some other device includes smartphone.
* can we connect the mifi to wall socket and leave it running 24-7? or better to get 3g wifi router instead?
