MIFI. (not MFI as someone once said to me) – They are basically a 3G usb dongle/datacard with a built in wireless router and a 4 hour battery (charged via normal USB)- You attach up to 5 devices to it wirelessly, all of them getting their internet from the 3G network. Really useful until you use them on a train – They simply do not have the same 3G signal pickup as a standard 3G usb dongle, rendering them pretty much useless on the move. I suspect there is some interference between the wireless signal and the 3G signal making the overall reception about 50% of normal.
My model was the Three Huawei e5830 – Wait for the new 585.
