Got an email from Sprint to update, I said YES and automatically my phone started updating to KitKat. Took about 30 minutes for the whole process, then got the bad news, more than 20 programs were missing, including Google Voice, which surprised me. It took me 3 hours to identify all the missing programs and then reinstall. My greatest fear was programs I had purchased and would have to deal with getting the developer to resolve it. Surprise, after installing the programs, I guess the framework was still there, but they acted just like they did before. I am back to normal, although a couple of programs that got deleted are no longer available or I can't find them.
Nothing about the upgrade jumps out at me, I guess I need to go and read the new features to see what I am getting. I need more time, but it does appear there is less battery drain.
I guess the wait is over for me, when is 5.0 coming out? I want it now!
