New firmware for Verizon MiFi is now available. If you only ever connect to your MiFi via WiFi, its entirely possible you will never see a notice that the firmware upgrade is available.
Verizon has yet to put out any official release notes to explain what the new firmware changes... but there are rumors out there, and we have been able to confirm the following:
The Verizon MiFi will not automatically turn on its WiFi hotspot feature when plugged into its a/c wall charger.
The Verizon MiFi's web admin now shows an animated battery icon while it is being charged.
