Short answer, no. I know the dumb-asses over at verizon are trying to tell everyone that you can but as of right now there is no way to roll back from the leak.
But in http://androidforums.com/all-things...ot-thread-apps-roms-updated-05-06-2010-a.html It says there is a way to downgrade.
and if you read the huge, red text in that thread you would not that it is NOT for leak users. It is for people that rooted to 2.1 only. You cannot downgrade or root once installing a leaked version. /thread.
