So I hate to be that guy, but I haven't really seen a good answer for this question:
Two days ago I updated to the first Froyo release. I was able to keep basically all my apps, but it took me forever to redo all my settings and reconfigure the apps, just like what happened with the 2.0 to 2.1 update.
Will I be able to load up this new build on the first post while being able to keep all my settings and whatnot?
Yes, a wipe isn't necessary and everything should be the same when you get done.
