Ok here's my experience... this is one bad ass phone yo!
First I downloaded the official leaked OTA from AndroidCentral onto my computer. But I didn't have my USB cable with me (visiting my sister), so I installed ADB Wireless so I could push it onto my phone over wifi. Well, once I got into it I didn't have any clue as to how to retrieve it off of my computer and put it on my phone. Sooooo... I just punched in the address into the address bar on the browser on my phone, and downloaded it straight onto my SD card from there!
Next, I rebooted into recovery, and tried to install it... it said the update zip did not exist. What??? Ok, went back and reread the instructions. It said to place the update zip on the root of my SD card... wasn't so sure what that meant at first. So I went into Root Explorer (first time I've ever used that app to be honest) and looked at my SD card looking for something that said 'root' on it. I found my download folder, opened it up and saw the update zip inside. Then it dawned on me, I needed to move it out of that folder and onto the card itself (ah ha, so that's what 'root' of the SD card meant!). So I very easily moved it out of the download folder, and onto the card itself.
Ok, repeat previous steps, rebooted into recovery... install zip from SD card... voila, SUCCESS!!!! How sweet is that, didn't even need a computer, just downloaded it straight from the phone itself onto it's own SD card, no middle man, no hassel. It did require a bit of thinking, but not so much that I broke a sweat or anything. This is cake, I'm loving this device, and really just today's technology as a whole, more and more each day!
