Verizon is finally giving the green light for the HTC ThunderBolt’s over-the-air- firmware update that brings along some fixes mainly to its 3G connectivity and GPS. Moreover, it’ll also provide owners better organization when it comes down to SMS and MMS messages. Naturally, the notification for the update should be there waiting for you, but if not, you can always initiate the manual process yourself to retrieve it.
The whole installation process should take approximately 2 minutes, and much like most updates, it would be a good idea to backup some of your important things just in case.
