I have taken delivery of a new gadget - a Huawei E5830 from Play.com.

This little device takes a mobile broadband SIM and creates a mini WiFi hotspot.  It came configured for the 3 network but after unlocking (courtesy of Zibri http://www.zibri.org/2010/05/e5830-free-unlock-released.html) while travelling on an East Coast train it works well on Vodafone.  I just needed to change the APN details.

APN - internet

Username - web

Password - web

All in all I am inpressed.  It works well with the iPod touch.
