That is correct and they have also fixed another error that is very close in numbers besides the last digit. Error 80188306.
I just wanted you to know that yes you will void your warranty, but you will be able to upgrade to the official Sprint version which leaves your warranty intact. Here is a posting of a customer who had a problem but Sprint was nice enough to give them a warrantee and replace their phone anyway. Most of Sprint reps and techs don't know a lot about Windows Phone OS in the stores so they give customers a new phone to fix the problem.
I figured it out. There was no problem with my OS; the phone was faulty. I had them replace the phone(for free, I might add), install all windows phone 8 updates and then I put the Dev back on it with all updates. It is working awesomely now. Thanks for the advice, Apocalypsead. As for sprint customer care, you guys need to get on the ball. There should be no reason why your subscribers should have more product knowledge than you! If we asked you a question about Android, iOS or even Blackberry you would be able to support it. Like it or not, you guys need to get trained and updated on how to support a Windows Phone. And you may ask yourself who am I and why do I feel this way: I am a former trainer for Sprint who made sure that all of my classes were on their game concerning all products that we supported.
