I just wanted to say thanks to John Clark for providing this how-to and all the other great info he and others post here.

I just did the update to .139 and it went very well. It did a couple of things I wasn't really expecting, like deleting all my apps and my themes, but that's okay - I can just reinstall anything that went away.

I'd have never made it without this thread and a bunch of searches which answered all the questions I've had so far. I'm grateful to all of you!

Happy holidays. =)
