Earlier today, HTC officially announced via their website that the Rezound’s Android 4.0.3 Ice Cream Sandwich OTA update was available for installation. Oddly, Verizon Wireless was completely silent from their end. Normally, Verizon updates their support pages prior to an official update being pushed onto their devices.
For those that have been following the HTC Rezound leaks over the past 4 months (yes, the ICS leaks started that long ago), this update, Software Number: 3.14.605.10 710RD; Baseband Version:1.22.10.0421r, 1.22.10.0424r, is the exact same build from last weeks latest leak. If you’re already running that release, at this point, you’re as official as it gets.
Shortly after the installation instructions made their way onto the web, for whatever the reason, HTC removed the update information from their website. Thankfully, we were able to snag the entire contents of HTC’s installation instructions before they were removed. Remember folks, once something has been posted online, it’s pretty hard to completely, if ever, remove it.
