So I just got done installing the leaked OTA and rooting my phone, but now I've read conflicting reports that when Froyo comes out in a couple weeks, I won't be able to install it without going back to stock 2.1. Even worse, going back to stock means erasing all the data and apps on my phone. I was under the impression that one could use Titanium backup to make sure all apps, data, and settings can be re-imaged to the phone, but then I realized that Titanium only works if you have root, which I won't if I go back to stock. Sorry for being a noob, but when the official update comes out, how do I install it without losing all my data? Why can't I just install it on top of the rooted OTA update OS?
