When the offiicial ota update hits it will possibly include froyo but there is also a chance (maybe 50/50) that it will lock us out of root. If it doesn't this post is a moot point. Now you can't get a rom with the leaked update because of the change in radio performed to the phone, but you could always get a rom with just stock froyo (w/sense) ripped from it. Meaning: If the update closes the "hole" to root, you will have to revert to stock, install the leaked ota update, than install the stock froyo rom after someone rips it for us. So just a heads up for those that have the leaked update, just sit tight and see what the future holds before you unistall something you may need.
