Like other users, I am looking forward to a wireless internet connection for the next OpenSPOT, probably wifi or bluetooth. A possible option for the current hardware would be nice. My suggestion is using a broadband hotspot via USB tethering thru the USB charge cable. I looked for a hotspot with an RJ-45 internet jack, but there are none (at least that use battery or usb power).

There are several mini routers available that can connect to your hotspot and provide Ethernet to the Openspot. I use the GL-AR150 Mini Travel Router, it is powered by a micro USB just like your Openspot is. You can find this from several suppliers.. Google is your friend.
