Just a PSA to get a good backup app and backup your data. Last night, I updated the PRL and Profile on my Sprint Hero and it deleted all of my bookmarks and replaced them with a bunch of standard bookmarks (Google, Flickr, Facebook, MySpace, NYTimes, etc.) - none of which I use. Fortunately, I had downloaded a backup app on Monday and was able to restore mine very quickly. I'm somewhat surprised since, short of a full upgrade, I haven't known Sprint to push out stuff to overwrite personal info. I'll definitely keep an eye on this in the future because it bugs me.
