EVDOinfo.com has posted a complete review of the Sierra Wireless 3G/4G Mobile Hotspot called the Overdrive.  This review is not a 2 paragraph review, but a multi-paged review that has been worked on over the last 3 weeks.  EVDOinfo.com had MANY issues with the Overdrive at first and Sierra Wireless flew out an engineer to help diagnose some of the problems experienced in the Chicago area.  A new firmware has been released (1.07) and we based our review on the latest firmware (as of 2/27/2010).
