HTC Thunderbolt owners, listen up! If you've not already received your OTA update then we have good news for you -- it's now rolling out to everyone. Go ahead, check for updates it should be there waiting for you. As noted, the whole process should take about 2 minutes to complete in which case your phone will reboot and you will be all up to date on the software level.
If you all remember this update, from a few weeks back then you'll know both are one and the same so you can expect better 3G connectivity and GPS along with better organization of SMS and MMS messages. If for any reason you're having issues, don't be afraid to hop into the Android Central forums to seek out some help.
